I have 2 cats, 9 months old. One is getting huge, with a round tummy. The other is normal healthy build. They are brothers but look quite different.

I don't overfeed. I try to monitor what they get and feed them seperately, as the fat cat will certainly take more than his fair share given the chance. it's possible they are finding food in the wild, or at a neighbours house or something. It's strange that only one of them is getting so fat, though.

I'm at a loss as to what to do Any ideas? Should I get the weight loss dry food. They currently have dry food, purina, and the odd bit of meat.

Are you sure it's weight? If they're out and about a lot and catching things, it could be worms. Have you wormed them/him recently? There are a few other things that cause a swollen tummy too, is the rest of his health seeming ok?

Dry food does tend to put weight on. Both your cats are individuals and will weigh different. Have they being neutered as that could be a cause of it. If you do decide to put you cat on a diet i would ask your vet first. Its dangerous for cats to go on crash diets it can make them seriously ill. There is a name for it but i cant remember it.

I have 2 cats, one is almost 2 the others almost 4. Both go out. Both neutered. Both wormed. Eat the same but the 4 year old has a fat pouch under his tummy but the 2 year old don't.

Both very happy with loads of energy and forever chasing and knocking 19 bells of crap out of each other so I let them get on with it.

Thanks for advice. Well, I have given them both a worming tablet today, will see if the fat one loses weight overnight.

If not, I guess I'll have to try to reduce fatty's food intake, but he will pester all day long!

They are both neutered, and both quite active. Fatty can no longer squeeze throught the iron gates now, and gets left behind when the other one goes through the gaps no problem!

I have several cats. Most are neutered/speyed. I have 3 sisters and one brother. One of the sisters is huge the others are normal size. Has the fatter cat got a flabby belly at all. I know the father of them and he is huge and his mother is realy tiny.

One of mine is getting a little on the large side. I noticed her tummy getting bigger and bigger and she's always been a slim cat. I was getting a little worried so asked the vet about it when she went for her recent booster jabs and health check. He said it was just mammary fat and advised I cut down on her food.
She isn't really eating any more than she ever has but she was hit by a car last summer and left with a broken pelvis. She spent a month on cage rest. She doesn't go out so much now I think partly due to the weather and partly due to her fear of what happened. I think she also lost her place in the local cat community while she was housebound and not around to defend her territory. I'm hoping come the summer she will regain her activity level and start to lose the excess weight. I have cut her food down a bit on advice from the vet but although she's not getting any bigger, she's not getting any smaller either.

He is all round a big cat, but his tummy does seem to stick out. He's fit and active, maybe it's all muscle, he doesn't seem 'flabby' as such.

He is still too fat, after the worming. He just seems to be a bit of a food addict, which is quite waring.

Had a similar problem - I have two cats - one loves her food and the other is a "normal" eater and understand it is pretty much impossible to monitor one's eating. I split their meals into 4 a day (breakfast, lunch, supper and nighttime) and if they aren't asking for the last one, they don't get it! It seems to be working - but ask your vet first before doing anything. Also if it is dried food start weighing it out.

My guinness who is the biggest cat we have doesnt eat that much. He waits till all the others have finished before he starts. Whilst he was at the vets once the vet said he was big boned. His legs are realy big and large. His belly flops from side to side when he runs which he can do even though he is big.

My cat is starting to look a bit chubby too. I have tried to cut down on food but feel mean. Everytime I go into the kitchen he follows me in and expects something to eat.

I am going to give him a worming tablet this week, aren't they supposed to have one every three months.

I think your correct with the worming tablet. When i had maisey speyed a couple of months ago i told my vet if she needs anything give her it. The vet said she had worms and too treat her in the next day and the following month which i did. I am due to take her daughter too be speyed next friday and will get wormers for all the cats at the same time. When i take vera's sons to be neutered 2wks later i will get flea treament for all of them.

Yes, for Milbemax which hopefully is what you have as they are tiny and easy to get down. Drontals were a whole different ball-game...

Went to ask my neighbours if they'd mind looking after my cats next week, and found an answer as to why one of my cats is fat. They are giving him titbits and ......MILK. I was told not to give them milk as it's not good for them. I feel somewhat peeved that my neighbour is doing this, when I'm trying to regulate his diet. My other cat is still slim, as he's shyer so doesn't go round there.

So, mystery solved, but now a new problem, I've asked them not to feed or give milk to my fat cat, but I'm not sure they will comply. I don't want to be difficult, it's lovely that they like my cats, and are willing to feed them when I'm away. Oh dear!

My cat is seemingly tubby and she's not been catching things out (she's still young and we've only started letting her out under supervision). I think it's natural for kittens to become a little tubby as they're growing up. It's only worrying if they're obviously fat, particularly if they're older, which could mean you're feeding them too much.

Oh also - I've had experience with a cat who had thyriod problems which made her fat. If it's happening unexpectedly, you might want to see a vet about it...
