We found a 3-4 week old kitten on Tuesday. We started giving him powdered KMR. I tried to mix canned food in with it but he can't eat it yet. He was having a hard time just lapping up the formula. He has peed lot's of times in the litter box. But only pooped once on Thursday afternoon (on his own without stimulation in litter box). He has not pooped since then and it's now Sunday. Is this normal? Is there anything I should be doing? I have been rubbing his butt with a washcloth and sometimes that will make him pee a little but no luck with poop. Should I give him baby food since the kitten canned food isn't thin enough for him to lap up even when mixed with water or mostly formula? Would that help since he would be having more than just milk and getting actual food? He seems to be acting normal otherwise. Is it ok that he hasn't pooped? Is this normal or something to be concerned about? Since he has peed and pooped once on his own does this mean that he wouldn't need stimulation to poop? Thanks in advance.
