my cat will only eat tuna.

Hello there..just wondering can anybody give me any advice..my cat won't eat anything but tuna, she has lost weight and doesn't look happy.she also goes over to eat on the dirty litter. u think she's trying to tell me something? can anyone help?

I would get her to a vet asap. Weightloss in a cat can cause serious health complications. Eating litter could cause a blockage. I would take her in today.

Try mixing a little tuna with other foods to get her to eat something else. Tuna has mercury so you want to get her eating something else.

Good luck. I hope she's feeling better soon.

Do you mean canned tuna that humans eat, or for cats?  Because if it's for humans, this is particularly not healthy as it does not contain an essential needed nutrient, Taurine, that cats must have to survive (or certainly not near enough if it does have any).

If that is the case, at the very least, you need to get cat food which is tuna so it has the right vitamins, etc. for felines.  Then, you can try cutting it with other foods until you wean the cat from it entirely.  It's just not a healthy diet at all.  

Aside from that, your cat must see a vet asap.  If she is eating her litter, this can be very bad if it's clumping litter, which can certainly cause a blockage as already mentioned.  

she spits the litter out. phew! it can cause blockage ? i just seen her doing this a few times. thank u for your help
 

It was dry litter that they usually spill as they are coming out of litter tray. and also its feline tuna. i will take to vet to get her checked. i think its stress also..because i got new kitten about 9 months ago..and shes eats every ones food..have to separate them now. she still plays bubbles her favourite game..i guess thats something but will take her to get checked. thank u for your advice .

Ok, well at least that's good it's cat food and, it sounds like she isn't literally eating the litter as food per se.

Who knows?  It could all be related to the stress of the new kitten?  But, certainly it would be better to move them off any seafood and onto better proteins (chicken, turkey, beef, etc.)

Let us know what the vet says. Good luck!
