Is he new to you, what is his exact diet(type of pellets, hay, any other foods), and when the cecals first come out are they fully formed(look like a blackberry cluster) or are they pasty at all(before getting stepped on and smooshed)?
He is new as of 8 weeks old. Never owned a bunny before so doing alot of research. He is 3 1/2 mo . He generally passes his cecotrophs in the early evening. It's 5:00pm now and I can smell him! It comes out both ways, in clusters and on the floor and all over his bum. I feed him unlimited alfalfa, a little veggies in morning, and was feeding him a little amount of pellets. I ran out of pellets, and there is so many conflicting ideas on the web about if you should or shouldn't give them pellets and how much to feed a baby-ish bunny that I held off to see if that helped. It kinda did, but just ordered some highly recommended baby pellets from Sherwood. I have to comb out the ceco's from his fur which really makes him mad. I gathered some up from the litter box and put it with his veggies to see if maybe he would eat them that way, but sadly no. I know these are very nutritious from him, so quite concerned. Terrified of him getting GI Stasis.
At that age you should transfer him to non alfalfa hays, I can't diagnose without seeing him but generally alfalfa hay is too rich it's okay for the babies but by 4 months he should eat only grass hay like timothy or meadow or orchard etc and a small amount of pellets, also can you tell us what brand of pellets and ingredients and fibre, protein percentage. This is a common problem when you feed alfalfa-based pellets and also alfalfa hay this diet is too rich at his age and he misses his cecals. Now you don't do any sudden changes in his diet but gradually transfer him to grass hays mixing grass and alfalfa hays over a couple weeks, and also if your pellets (most likely) based on alfalfa you should get adult pellets without alfalfa or at least with lower protein level. Max 13% protein and min 19% fibre. Also by 4 months you should start limiting his portions as he doesn't need unlimited anymore.
I never feed alfalfa hay, only grass hays since birth and unlimited alfalfa-based pellets they start eating around 5 weeks of age, but by 4 months their pellets are limited. Otherwise they start getting very fat by 4,5 months.
So I would suggest transferring him to grass hays from alfalfa by mixing for a week or two and gradually decreasing alfalfa and increasing hay, and I see now you feed Sherwood baby pellets they are alfalfa based, you can also move him (gradually) to non-alfalfa adult pellets.
This should fix your problems. The reason I don't feed alfalfa hay is because baby pellets are all alfalfa based and it's enough for them, also after alfalfa hay they often won't eat regular hays but they need them, by 4 months they should eat unlimited grass hay, not alfalfa, and a small amount of max 13% protein pellets. Vegetables and greens usually start adding from 4-6 months, in limited amounts, introducing slowly, one type at a time.
