My 9 month old (approx) neutered bunny usually has a huge appetite. He's always eager for food (greens, hay, pellets) and I feed him pellets and fresh veggies twice a day and refill his hay every night. He always wants more. But not today. He is eating some and has pooped and peed but not nearly as much as normal. He ate only half his pellets, wasn't interested in lettuce and chewed on other veggies but not with his usual exuberance. He has been eating some hay throughout the day too. He's also not as active as he usually is. Is this unusual? It's been about 24 hours. (Like I said, he has pooped and peed several times in that time, but not as much as usual)

He did this once before about a month ago and then was back to normal. That was on a really hot day though so I thought maybe his energy was sapped from the heat. It has not been hot today.

Thanks for any input. I've only had him about 2 months and he's my first bunny.

It's often our first clue that something is up. Has there been anything change about the house? Noise that may have caused stress?

Is he sitting hunched up or pressing his belly down much?

Sometimes a bit of gas pain upsets them and a tummy massage and some infant simethicone helps give relief. It wouldnt hurt to try those things if you suspect some gas. My girl bun used to press belly down or keep repositioning herself when she had gas.

It's good he is eating and toileting some.

With the weekend approaching it might be an idea to schedule a vet visit within the next day just in case there is something else causing his loss of appetite.

Hope he's back to normal soon!

It sounds like a bit of a slow down, but not stasis if he's still eating, peeing and pooping. Like Jersey asked, if there have been any changes in the house at all that could have just interrupted his routine? IF not, he might be on the path to a slowdown so the best thing you can do is encourage eating (keep offering fresh food-just take the old out and freshen it up-hay, pellets, veggies) and get him moving -maybe try letting him out in a new room to explore, or even move some furniture around-newness prompts exploring and movement is the best thing for getting the GI tract moving again.
