I've been feeding a stray kitty for a couple of months now. He really loves wet food . He/she has a huge appetite. I put out two 5.5 oz cans of Friskies Pate and he licks the dish clean and sometimes eats a bit of kibble. Is it normal for a cat to have such a big appetite? He looks pretty healthy. There's no way I can touch him much less take him to the vet or anything . He's very skittish.
