I will call the vet today and see if I can get him in. Unfortunately I am at work until after the vet closes. 🙁
If his teeth are bothering him would he still be eating his boxes and papers? We have always tried to give him a good variety of safe boxes and papers to keep his teeth in good shape. Maybe we gave him too much and now his little system is all gummed up.

He always has plenty of hay, and he ate a little of it yesterday. Usually he goes through a handful in a day or two though.

Ok, I have made an appointment to drop him off at the Vet’s tomorrow. Hopefully he will eat a little bit today and start feeling better. I would like nothing more than for him to be right as rain tomorrow and have to cancel the appointment,but I would rather be safe than sorry.

He is going through a big shedding right now, could it be a hairball like cat’s get? I know bunnies can’t throw up but I am not sure if they get hairballs.
I hate feeling so helpless, I just wish he could tell me what was wrong and how to fix it.

Good to know! Thanks I will have the vet check his teeth to be sure. He was eating like a horse last week, almost twice what he normally eats and I thought he was going through a growth spurt or something. It’s just so disconcerting to have him go from eating so well to hardly eating anything.

Well, Dex went to see Dr. Casey today and he did great. I was worried that he would give them fits since he greatly dislikes to be held, but he was a champ and let them weigh him and check his stomach and even did well during his x-rays. The vet didn’t see any obvious blockages but he does believe he has GI Stasis and some gas. He gave us some medicine and we were instructed to get some Oxbow Critical Care food so that we can force feed him something with lots of fiber to get his system moving at the right pace again, and were also told to try canned pumpkin since it’s relatively sweet (so he will think it’s a treat) and it is very high in fiber. I had to go to right work after taking him home and he was sitting in his cage mad at me and pouting when I left, but I think he will forgive me. Fingers crossed that he will have eaten some of the pumpkin by the time I get home. Thanks for all of your support and advice. I will update again when I have more news.

Thank you @tanlover14!

We were unable to find any Critical Care in our area, GRRRRR! So I have been making a “Fiber Smoothie” for Dex by putting hay, pellets, leafy greens, cilantro, tomatoes, canned pumpkin and a little apple juice and water in the blender, then force feeding him that until we can find some Critical Care and get it here. His poops are now odd shaped and a little watery.

Is this a good thing?

We have been giving him his medicine as well, we just hope that it’s helping and his system will straighten up soon. We just want our bunny back to normal!

We found some Critical Care in our area, finally! We will start giving him that tonight so we are excited to hopefully see some good results.

Dex did nibble at some wet romaine lettuce last night, and this morning so that is good. We are also still seeing a few new little mishapen poops in his litterbox every so often. He has all but stopped running around the house though and this worries me, but I think about when I am sick and I don’t feel like running around the house either so I am trying not to be too concerned.

My husband has been giving him a little bit of fresh pineapple juice because he read somewhere that it helps, but in the article that BB referenced (thanks so much, it was very informative) it says not to give them the fresh stuff because the sugar could make his problem worse.

Does anyone have any idea which is right? Give it to him or not give it to him?

Thanks for your help and healing vibes! We hope to have our boy hopping around like normal again soon!

Thanks to tanlover and LPT for your input on the pineapple juice! We have stopped giving it to him and we have now had three feedings of the Critical Care and Dex seems to be coming back to his normal self.

His activity level jumped a notch last night and he was hopping around the house almost as usual. He was acting out a bit though and it has us scratching our heads. Dex usually does not chew on furniture and if he does I usually just have to tell him once to get his teeth off my furniture and he does. Last night he would not stop chewing on our table and chair legs, even our floor! If I shooed him away from one piece of furniture he would hop off and find another to chew on. We were pretty happy that he was hopping around so we tried to be chill about it and chalk it up to him finally feeling better and needing to burn off some energy. He also put himself to bed last night without us having to “herd” him into his cage. Other than the weird behavior (we aren’t complaining, we are just glad he is still with us and feeling better) he seems to be pooping more, still small and misshapen but more than the last few days, so we are glad for that as well.

So good reports and high hopes for a full recovery soon. Thank you all for your input, support, and healing vibes. It’s nice to know there is a place for people with bunny friends who understand each other!
