I can’t really advise on the critical care issue because I’ve only used it during stasis, where there’s always going to be small poops! Does he get stressed by the process?

Have you tried other weight gaining foods, like a sprinkle of oats?

I also wonder if it’s just that he’s naturally tiny and it’s nothing to worry about – 750 is normal for him.Nimbus weighs 1kg, which I know is your dream, but actually that’s around half the weight of most lionheads. He’s just a tiny bun, but he’s healthy so I’ve left him be.

Cant answer your CC question, thw only thought is its stressing him out or the mixture isnt wet enough?
I use oats and sunflower seeds to add weight to scrawny bunnies tbh, most of them hated CC and I dont think it adds as much weight as the other things do.

750 does seem small, but like S&L says, as long as he is eating healthy and being a regular active bun I wouldnt be overly concerned, that might just be the way he is

If you think about it, cc has a lot of fiber but also alotnpf digestible nutrients and comparing to regular food that has a lot of indigestible fiber, that’s why their poop is so large coming out since so much of it is a waste. Cc has so much that isn’t waste that often times the poop is small because not a lot is left over. It seems like it would be the opposite. You could try to wean him off of it and see if that helps improve. Because if his gi system wasn’t working, then you’d get huge poops as everything kinda clumps together. My Dutch has small poops but he’s been like that forever. Have you thought of maybe supplementing alfalfa a tiny bit for help with weight gain?

Ah, I’d forgotten just how small Kurotta is! Wick is 1,202g, so pretty much smack at the ideal top range for a nethie. I think you’re familiar with when I had to do CC supplement when he was younger because he was underweight for a spell.

It’s great that you’re feeling the “comfort” layer above the spine — especially because you’re now accustomed to how Kurotta’s fat may distribute itself.

I agree with BH, in that when I think of larger poop sizes, I actually think about indigestible fibers. Hay has large, indigestible fibers, while pellets and CC have crushed fibers. To an extent, it makes sense that poops may be smaller because Kurotta is releasing that CC and/or not eating as much hay as before as a result of the supplement.

I also want to echo S&L, in that if you find his current weight is healthy for his body size, that’s fine. He could be on the smaller version of a dwarf, while Wick is on the large end. What’s most important is how you perceive him. If you think he could put on some more grams in order to feel a bit healthier, than that’s fine.

All the advice you’ve received is great so far! I just wanted to pop in and say that my Nethie Ollie weighs in at right around 2.5 pounds (1.13 kilos??) and I’ve always noticed that his poop is smaller than my other rabbit Leo who is just over 5 pounds. I think it’s quite possible for that to be the norm for a smaller breed!

CC has more fiber than greens but I think a lot less than hay so it makes sense that his poops get smaller on it. It might process differently too from not having pieces.
