How old is tikeya? If she is under a few years of age it is *probably* not related to a thyroid problem. Has she been gaining weight fairly suddenly or is it barely noticable over a long period of time? How long have you been feeding her 2 cups a day? Is she on a low calorie food? If so how long has she been on it for?

Here is a site w/ thyroid info http://thyroid.about.com/cs/catsdogspets/

I find it odd that you went to multiple vets & care hospitals (which are the same things here in NY just a different name) anyways none had mentioned anything about thyroid even when you mentioned a weight problem (& obviousally they could see the weight problem) I would be seeking for yet another vet. I could understand that if you had only been to one then I would mention something to them, sometimes they may have a bad day or whatever & just forget or overlook a thyroid prob.) but to have 5 different ones do it thats really strange. UNLESS & she is very young maybe under 2 or 3 years of age AND is getting only 2 cups a day (including treats & what not).



I have tikeya on as low as food amount as if possible for her, she freaks out whining and crying if she only gets half a cup a day, i also think that is kinda crule.. ugh..
I have a 13 year old 70lb shep/husky mix & he gets only 3/4 cup of nutro natural choice for large breeds. He has had a weight problem since he turned about 3-4 & especially back then has always gotten plenty of excersize & good food. I had him checked multiple times for thryoid problems even the vets could not believe that it turned out a-ok. So we tested for other things & could find nothing.
Anyways guess just he has a really really low metabolism. I have had him on this amount for years (even tried other foods) but it kinda took his belly a little while to shrink so he would not mind being fed less but I did it gradually. And for the first year I did this I fed him 3 times a day It made him think he was actually being fed more than normal.

If all else fails feed less actual food & add a little filler (like canned pumpkin or green beans)
