So I have an abondon kitten about 2 weeks or what not. He was belly dragging and eyes sealed last week. This week he's off thaw ground and bright eyed. My concern is ... I have a feral cat indoor/ out door male. If he has his ear tipped does that mean he has all shots as well. Don't want newbie to get him sick. He's up to date on rabies. Also is thawed something I can give kitten ( SIMBA) to help his amuine system? He did not get anything through mommas milk so...
