Having a problem with my cat (pic unrelated)
She only eats wet food, and only the gravy off of the wet food. And shes a little underweight/bony. Shes too picky of an eater
Go to vet.
We have another thread right now from someone whose cat was too thin for too long he had to be euthanized.
Your cat may have an abcess, infected tooth or kidney problems. Gravy is not enough to keep it alive.
