I've got two 4 week old kittens I took from a feral mom. I started them on solid food last night. One did great. The other is acting really strange. His belly feels all bloated and he is dragging his back legs as if they are paralyzed. I fed him once yesterday evening and once about 2 this morning, not knowing I had to wipe his behind. I just now wiped his behind (4:30 a.m.) but he has not pooped that I can see. Has anyone seen this wierd behavior before? thx
