Wet a paper towel with warm water and wipe it's butt. It might take a minute or two but it will work because the mom licks them. Keep feeding the formula on a few hour schedule and after it eats then mak it use the bathroom.
when we would take care of our puppies when the mother ignored them, we would also rub their tummy very very gently about an hour or so after feeding them. The vet said sometimes it helps relax them and help get things moving. I've never tried it on a cat though.
Thanks. I've been using a wash rag. Maybe it needs to be softer. I'll try rubbing his tummy. Thanks. (;
i used a dry paper towel and just patted the kittens bums and it worked... i never wetted it and i cant say i was very gentle either... hopefully you can get them going :)
