Did it ever come out? I am having a similar situation... In late November I noticed a hair in Simba's butt. I just cut off what was dangling out and it seemed like it slowly went away. All of the sudden, yesterday (a month later!) I realized that the hair was not gone. Whenever Simba poops, I can see a little bit of the hair poking out but then it gets sucked back in after his poop. I am certain it is the same hair because ever since I found it back in November I have been super cautious about tying my hair back when making his food and making sure no hairs are in his enclosure.While soaking little Skurt earlier I noticed he was walking around with poop sticking out of his rear. At first I just thought he was pooping and let him soak a little longer. But it wouldn't come out. I got some toilet paper and pulled it out and noticed it was caught on hair that is hanging out of his butt!
So I'm afraid to pull it out because I don't know what's it's wrapped around in there but will he poop it out on his own or is this a vet thing? BTW I'm sad to say it's totally my hair. It must have fallen in his food bowl and he ate it.
