my boyfriends dads cat had 3 kittens.. they are approximately 3 weeks old right now.. they crawl around.. but arent walking yet.. and of course they are still nursing on their mother.. anyway.. the kittens are kept inside in a little basket.. and the mama cat stays inside also. everytime me and my boyfriend go over there, we let the mama out to use the bathroom, and she comes back.. well anyway, yesterday my boyfriend went over there and when he left, apparently the mama cat darted out of the door and my boyfriend didnt even notice.. and we went back there today to find that the mama wasnt with her kittens.. they were meowing sooo loud.. they were sooo hungry, and we couldnt find the mama anywhere... we looked everywhere inside (b/c he isnt sure that she actually went outside) and we called and called for her outside... but she didnt come.. and she always comes when we call her.. so we are worried that she either did get outside and got hit by a car, or that she didnt get outside and that she is dead somewhere in the house.. its a two story house that is pretty cluttered so she could be anywhere).. we fed the kittens with a bottle and some milk replacement for kitties.. and they finally stopped whining and went to sleep.. we are going to keep going over there and doing it as much as we possibly can.. what what are some other tips on taking care of 3 week old kittens? i heard you are supposed to kinda wipe their butts with a warm cotten ball the make them poo.. but what else should we be doing if the mama cat never comes back? is their chance of survival good? please help, i would hate to see these kitties die or become very ill.. i just want to help them if i can.
