Suddenly, without warning, meee exclaimed (16-Sep-05 9:57 AM):

Cereals as the first ingredient is probably why she's gassy.  Try to
find something with meat (by-products are ok, if you can't afford the
real premium stuff) as the first ingredient.  Yes, you'll pay more.
Yes, you'll have to experiment.  I've also got a fussy cat and I've lost
track of the food I've given away or thrown away 'cause she won't eat it.

 I think TomCat is probably very similar to Felix in the UK or ....
augh, another cat-named food that escapes me for the moment in the US.
It sounds like you're only feeding her canned.  You might try feeding
her a quality dry food as well, for her teeth, and because you might
find something higher quality that she'll enjoy.

I know you don't think you have the $$ to pay for better food, but you
really need to try.  She might even prefer one with a high meat content
- perhaps try something tuna.  My cat rarely turns down anything with
tuna.  You might also talk to your vet - might have free samples of
whatever food they have on offer.  If you have some good quality pet
stores in the area, you might ask for free samples there too - lots of
the premium foods do offer them.

Good luck.  I know how difficult it can be.  My cat, Meep, would only
eat dry Iams Ocean Fish for most of her life.  Then, suddenly about 1.5
years ago, she wouldn't eat it any more.  I had to search around for
something else palatable.  Fortunately, as far as dry foods go, she's
much more willing now that she's older to accept other brands.

Not so with the canned/wet foods though.  The search goes on.  I'm stuck
mostly with Felix bags presently, which is grocery-store brand as well.
 My vet calls it 'junk food'.  I can get her to eat some of the Iams
canned, but not consistently.
