Overweight cat.

poor kitty!

maybe she

a) has diabetes. I've heard that that can sometimes make people gain weight.
or
b) just feels like being a kitty couch potato.

Anyway, good luck!

I've been reading up on vitamin E in cats, and it turns out that in sufficient quantity it's something of an appetite suppressant. Try puncturing a vitamin E capsule and letting her lick it off your fingers (apparently it tastes really good - not to me, but my cat assures me it's delicious). See if she's still such a vacuum cleaner after a few days of that. At least according to this website, cats haven't been shown to be capable of overdosing on vitamin E.

Love, Columbine (who has a hard time rubbing it on Smudge's ouchies because he wants to lick it all immediately, and he's now refusing even his beloved CET Chews...)

Hi Fatcat...how's she getting on?

How old is she, and your other cat? You may want to consider giving them Senior food, as it is lower in calories.
Due to Cochise being overweight, that is the solution my vet recommended for my multi-cat household.
