I posted this on backyardherds but wanted to post here to due to the urgency of the situation. My neighbor pulled into my driveway about a half an hour ago with a "surprise" for me. He has rabbits that apparently had "gotten loose" on his property once and now they reproduce in the woods and run wild. But that's a whole other topic. Anyway, he saw some neighborhood dogs chasing a baby bunny in his yard so he rescued it and gave it to me as a surprise. He's an older guy, and was trying to be nice, not realizing I carefully research pets before taking on this kind of responsibility. I told him I don't even have a rabbit hutch or anything and he said to just put him in with my chickens. So he left, and I'm wandering around the yard in shock with a baby bunny in my hand. I decided go online and do some rabbit research to see what this little guy needs. My neighbor says he's a "New Zealand" and is about 2 or 3 weeks old, but I know nothing about rabbits, so this means little to me. Just as I was about to put him in my hen house for now since it's empty during the day, I saw a flea on her. Upon further inspection I found lots of flea dust and several living fleas. Now I'm really panicked, I don't want fleas in my house, I have two indoor cats, and I'm not sure about the chickens, but I imagine they could get fleas too, right? Does anyone have any advice as far as general care for the bunny, but also what I can do about the fleas?! Can I just use cat flea stuff? Any ideas where I can keep him segregated until the fleas are gone? I don't want to spread them to my other animals. I don't have a barn or any outbuildings other than the coop with the chickens and a shed which gets very hot. Right now the poor little thing is in a cardboard box in the yard until I figure out a better plan, so any advice would be appreciated. People should not give live animals as surprise gifts, but all I can do now is try and give him a good home and tell my neighbor thanks but never do this again! PS: Just remembered I have a Guinea Pig cage instead of the box, but still not sure where to put the cage given the flea situation!
