The kitten was the only one of the litter, mother was smaller then the average cat so I don’t know if that was the reason. It was fed by the mother for a good 7 days. We tried to keep mom in my room, but she quickly got into heat and ended up running out a open window and left her newborn alone. We bought KMR prior and tried feeding the newborn ourselves, she put up a fight and didn’t drink much, she did have yellow pee and a tiny bit of poop if you could even all it that[very tiny dots]. About 16 hours later we found the mother and tried to show her the kitten but she hissed and swatted at it. It was very heartbreaking and she continued to do so we gave up and started bottle feeding again and stimulating. We tried calling shelters and contacting a friend who had a cat who just had kittens to see if we could find a foster mom, but both rejected us. We did notice its anus bulging out a bit but we hoped it would go down the next day. Kitten soon got used to the bottle the next day and slept all the time but when woken up she crawled everywhere and was very strong and vocal and hated getting her genitals wiped. Her anus still had not gone down, so we took her to the vet. They took her temperature, and the vet came in and saw us for about not even 10 minutes. We asked about the anus and the vet said it could be from not pooping and she was probably constipated, and didn’t offer help on that subject. We asked how to relieve the kitten’s constipation, and all he said was to stimulate. Which we have been doing and all she does is pee. Basically all he told us in that short time was that she was healthy and charged us. I’ve been desperately looking online and have tried about everything. From that triangle method[I think we did it right?] to giving her drops of mineral oil in the KMR, watering down the KMR, and running her bottom under warm water. Every time we do try to make her poop she cries and squirms around and makes it really hard to see if anything is coming out. Her anus is back to normal size again. She has farted twice since then, and her pee is no longer yellow but clearish. She looks healthy, she purrs after fed, and her eyes have opened, still very active and vocal since the day we took over. I can’t tell if she is bloated or if that’s just how they look. It’s been 4 days since we took over and switched to KMR and still no poop just pee. Are we doing something wrong? Is she even producing poop if that’s possible? Please help, I don’t want to have to take her to the vet again so soon. Sorry for the long wall of text.
