My bunny won't eat hay or pellets after I changed his diet. Why?

Updated On September 23rd, 2025

Pet's info: Small Animal | Rabbit | Male | unneutered | 2 months and 2 days old

my king is a 2 months old double mane lion head bunny. i’ve been feeding him pellets,hay, lettuce, and very thin sliced cucumbers. i took him off the lettuce and cucumbers a few days ago because i notice he wasn’t eating his hay or pellets. now i’m starting to get worried because he just nibbles on his hay or pellets little by little. his poop looks normal to me and it’s not dry. I wanna know what’s wrong with my baby. is it because he’s coming of age? or is he stress? what’s wrong with him?

Your bunny was probably just used to eating the lettuce and is adjusting to his new diet. You did the right thing by offering him only the pellets and hay. This is what is most beneficial to him. Since his stools are normal I would not worry at this point. If he stops passing stools, stops eating, or if you suspect he is losing weight, then you should take him to the veterinarian to be checked out. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

    Make sure he has only hay to eat and some leafy green vegetables. He has small poop because he is not eating. If he isn't eating hay/greens then he needs to see a vet as he may have a dental problem. If he is smelly you can give him a bath. https://www.youtube.com/watch?v=TqNaUk4U7Ao

    Keep him warm and make sure he continues to eat. As long as he is eating and drinking, he will defecate eventually. Monitor for lethargy and loss of appetite. As a new pet, he should be examine by your veterinarian to confirm good health or to diagnose and treat any pre-existing conditions. He can eat timothy hay, oat hay and similar grasses as well as alfalfa. Offer commercial pellets in limited quantities to prevent obesity. Fresh greens and vegetables should be offered gradually and in small amounts initially to allow his system to acclimate to different foods.
