If he's not pooping at all I would call a vet, I had a rabbit die from being impacted, it went really fast. My vet did recommend mineral oil but that was for a rabbit who was still passing very small, hard, dry pellets. Then more roughage and exercise to help prevent it. But if he's not pooping at all he needs help right away.
He is still pooping a bit, not much though. And he did not eat his food last night.
Funny, when I google--constipated rabbit--I don't get anything close to pertinent info. It does sound like statis. I will not bring to a vet--he is a meat rabbit. I will try all I can to help him. We have given him simethicone, yogurt, let him run around the yard, and right now he is in my laundry room with access to hay yogurt and water. We have massaged him ,we will monitor him, and I will read your page PBP.
Thank you to all of you who responded. I am still miffed that when I tried to look for info on the 'net, I got nothing.
Three cheers to BYC, and BYH, where I also got a response!!!!!!!
A handy item to have on hand is Petromalt or a similar product, sold in pet (And probably some feed stores) for hairballs. If you can't find it with the rabbit stuff, check the cat section and just get the one that isn't meat flavored. This stuff works great, especially if you catch the potential obstruction early.
