My 7 year old male cat was fine until I brought another cat into the picture. Tucker was a fat cat that was seemingly healthy till I adopted Bean. They get along fine, they play, cuddle and co exist great. But Tucker has been getting thinner and thinner. We have not changed food at all, no change of litter or anything like that either. We dont have money to take him to the vet right now, but does anyone know if this is an emergency or if Tucker just has anxiety from Bean maybe? Please help!
