Frequently Asked Questions: The Big House – A Chonky Cat Rescue

1. What inspired the creation of a cat rescue exclusively for extremely overweight cats?

The idea came after adopting one of the world's largest cats, who weighed 43.2 lbs. As we shared his journey online, people began reaching out for help with their own overweight cats. We realized there were no specific rescues dedicated to feline obesity—even though similar ones exist for seniors, kittens, or feral cats. With obesity on the rise in animals and overweight cats often being overlooked or euthanized, we knew it was time to create something just for them.

2. How is your Rescue different from a veterinary clinic?

We’re not a veterinary practice—we’re an animal rescue that partners with vets and rehab professionals. This gives us more flexibility and a low-pressure environment, but our success wouldn't be possible without those expert partnerships we've developed.

3. How does behavioral research factor into your approach?

Behavioral research plays a big role. Obesity isn’t just about diet—it’s about habits like food-seeking, inactivity, and emotional eating. We use behavioral insights to tailor strategies like puzzle feeders, routine changes, and stress-reducing methods to each cat. This helps create long-term success.

4. What’s a typical daily routine for a cat in your program?

Cats live in a home-like environment with personalized diet and exercise plans. Some focus on basic life skills (like using the litter box, being able to engage in play), while others do mini fitness sessions throughout the day. The goal is to gradually build mobility and strength in a way that suits each cat’s condition. A typical day varies based on their goals.

5. What kinds of therapy do you use to help cats lose weight?

Diet is key—about 80% of their weight loss comes from correct food portions. But as the weight drops, cats gain mobility, which then supports further weight loss. It’s a full-body process involving dietary changes and physical activity.

6. Do you offer exercise therapy for cats? What does it look like?

Yes! Cat-friendly training varies depending on the cat’s personality and physical ability. Some enjoy hydrotherapy (water treadmills), others prefer play-based workouts or agility-like activities. For those with mobility issues, we use creative setups like memory foam mats to gently build muscle. All cats have to work for their meals—whether via puzzle feeders, lick mats, or treat trails. It's important to note, exercise isn't about burning calories to us, although it helps. It is about increasing mobility and improving quality of life.

7. How long does a typical feline weight loss program take?

It can take months to years depending on how overweight the cat is. Weight loss must be slow and steady to avoid complications like fatty liver disease. We usually adopt cats out before they reach their goal weight but ensure new owners are equipped to continue the plan.

8. What are the criteria for cats to join the program?

Cats must meet two different criteria to enter our Rescue. The cat must be morbidly obese with a body score 9/9+ and far above breed average, typically over 30+ pounds. They must also be at risk—either in a shelter, rescue, facing euthanasia or at imminent risk of death due to obesity related complications.

Most of our cats come from shelters, but we also accept owner surrenders in urgent cases i.e. parent has passed away or entered long term care. We do not offer a weight-loss service for owned cats. Unfortunately with our limited size and resources, we can only accept cats who meet that criteria.

A typical overweight cat can often be supported adequately in their current shelter or rescue. This is where our support program for those organizations comes in handy!

9. How are diet plans developed for each cat?

We calculate calorie needs using a standard formula and then customize the plan based on the cat’s food preferences and any health conditions. Some need high fiber, others need prescription food. It's trial and error, just like with people. We do this under veterinary supervision.

10. Do you use home-cooked or alternative diets?

No, we use conventional ready-made pet foods. As we’re not veterinary nutritionists, we stick to commercially available options. Pet food and nutrition can be a polarizing topic. We aren't pro or against any method so long as it is a complete and balanced diet, do what works best for you & your pet!

11. How do you manage food frustration or stress during dieting?

“Hangry” is a real thing! We use enrichment like toys, extra attention, and puzzle feeders to distract them. Some need smaller, more frequent meals to cope, and we avoid restrictive methods that increase stress. In some cases changing the diet can also help, for example using one that makes them feel fuller longer.

12. How involved are owners in the weight loss process?

We don’t return cats to former owners—ours are typically surrendered or shelter cats. But we do support other owners informally, and their involvement is critical. Cats only eat what we give them, so it’s often a matter of human behavior, too.

13. Isn’t it stressful for cats to leave home, meet other cats, and go on a diet?

Yes, it can be. Most of our cats have already been surrendered, often due to obesity-related problems so they come stressed. We move slowly, ensuring a full health check before starting any diet. If a cat isn’t fit for our setup, we refer them to foster-based rescues and support remotely.

14. Is there aftercare to avoid yo-yo dieting?

Absolutely. We support adopters with follow-ups, provide food, scales, and connections to vet clinics. We’re always available by phone or email.

15. Any success stories that stand out?

Walter’s story is unforgettable. He was overweight and diabetic, scheduled for euthanasia, but we pulled him just in time. Through diet, his diabetes was reversed, he lost weight, and now thrives in a loving home. His adopters make me laugh often with update photos. He was obsessed with this catnip pumpkin so they went out and bought 5 so he never loses one. It's his favourite toy that keeps him active.

16. What causes obesity in cats—overfeeding or lack of exercise?

Primarily overfeeding, at least in our experience. Of course there are many medical conditions that can contribute to obesity as well but free-feeding seems very common and not all cats can self-regulate. Lack of exercise also contributes—cats need stimulation and play just like dogs. They are often thought of as low-maintenance pets but they have needs too.

17. Is it true a cat’s liver becomes fatty after 72 hours without food?

Yes. It’s a serious condition and potentially fatal. We’ve even used appetite stimulants when cats were too stressed to eat. This is always our biggest fear when taking an overweight cat in and we work hard to prevent this complication. This is a good reason why diet and weight-loss should be done gradually and with veterinary supervision.

18. Do people misunderstand how much a cat should eat?

I believe so, cat portion sizes are smaller than most realize. We encourage everyone to read their food packaging and be honest about how much their cat is actually eating. You may be surprised to see the portions you are providing are over the recommended guidelines.

19. What should food manufacturers improve?

They need to list calories and carbohydrates clearly on packaging. It’s frustrating to find that info, even for us. Labels that are easier to read would help pet owners make more informed decisions. Drop the buzz words and get back to basics.

20. When is a cat officially overweight?

If they’re 10–20% over their ideal weight or lack a visible waist from above, they’re likely overweight. Even half a kilo extra significantly increases health risks.

21. Do overweight cats need special consideration during exercise?

Yes. Always consult a Veterinarian before starting exercise with your overweight cat. Their joints may already be strained, there could be underlying health issues and cats hide pain well. Once your vet clears you to start, begin slowly and work within their comfort zone. You may also benefit from a referral to a rehabilitation center for animals to help guide you.

22. Can cats really use underwater treadmills?

Yes! Some tolerate it very well. With patience, warm water, and encouragement, it can become a beneficial and even enjoyable part of their routine—always under professional supervision.

23. How is The Big House funded?

We are funded completely on the generosity of those who support us online and in our community, through donations. 100% of donated funds go directly to the cats and their care. We do not receive Government Funding.

24. If you could give any advice to owners of overweight cats, what would it be?

Start with a visit to your veterinary team, rule out any medical reasons for the possible weight gain and if there are, have them treated.

If there are no medical reasons, take a look within and really ask yourself if you may be overfeeding your cat. No judgement, we have all done it, including me. Are you giving too many treats, maybe free feeding or providing portions that are too big? Diet food is great but it isn't a miracle worker. If you have ever heard the saying, you can't outrun a bad diet, it applies here. We can't help our pets if we don't start with a little self reflection and see if we are contributing to or helping the issue. Once you know better, you do better.

Start small, maybe with just feeding proper portions (you may need to take time to slowly work down to that portion, never reduce food quickly). You can use the existing food you have and go from there.

My other advice would be that a lot of cat owners already understand that diet matters, but what’s often overlooked is how much cats actually need to move and engage with their environment. We tend to think of cats as low-maintenance or independent, but the truth is, they need enrichment and stimulation just like dogs do.

Think of your cat not just as a pet, but as a predator, an athlete, a curious explorer. Cats are natural hunters, and when we take away the need to hunt, we also take away a major part of their daily movement and mental activity. Play, puzzle feeders, food games, climbing, chasing, exploring—it all helps. And it doesn’t have to be complicated! Scatter their food, use a laser pointer, build a little obstacle course out of boxes. Just get them moving and thinking.

Weight loss isn’t just about less food—it’s about a more fulfilling life. Your cat deserves that.

25. What do you hope to accomplish with this Sanctuary?

Our big dream (pun absolutely intended) is to change the narrative around overweight cats. With over 60% of domestic cats now overweight, we’re seeing more and more of them ending up in shelters due to obesity-related health issues. Sadly, many of these cats are passed over—or worse, at risk of being euthanized—because of their medical needs.

We want to change that.

Our mission is to remove those barriers, get these cats healthy or at least on the right track, and showcase their strengths so they have a real shot at a second chance. These cats have so much personality, love, and life left to give—they just need someone to see past the scale.

Beyond that, we want to empower pet owners. Weight management doesn’t have to be complicated or expensive. Most people already have the tools at home to make meaningful changes—and if they don’t, we’ll figure it out together.

And yes, we’re also here to disrupt the online “chonky cat” culture. It’s time to shift the vibe from “haha, I love chonky cats” to “look at this cat glow up!” Because let’s be honest—what’s better than a chonky cat? A healthy one who can jump, groom, play, and live their best life.
