Maybe look into providing him food that's high in protein another way, say cooked chicken or beef or turkey. I know there are a few threads on here discussing a balanced home made diet. I hope he is getting better :(
We recently adopted another cat from a shelter. He took 3 whole months to warm up to us and my other cat. Now he is begging for kisses and belly rubs. Sometimes you need to give them their space.
We acclimated Thorin, cat, to our house and other cat, Nero, by figuring out what his favorite toy...
My cat Nero is 2 years old and all black, I recently noticed a orangeish brown colored scab when i picked at it. he didn't like me messing with it (he doesn't like his back feet messed with as much) There wasn't any blood or anything, just super dry skin. I'm not sure if i want to go to my vet...
