Hi and congrats! Have you taken him to a rabbit savvy vet yet for a general check up? Only rabbit savvy vets should be used unless there is an emergency and you can’t contact the vet. There they can tell you if he has gas, Spurs on his teeth or any other pain.

What kind of pellets is his on? And kale has a lot of calcium in it so it’s not supposed to be given a lot as it can cause bladd sludge that leads to a UTI. I suggest taking Him to a rabbit savvy vet and they can tell you his proper diet and other important information. He might have some gas which is very painful and a vet can tell you how to treat him for it. Also, you might want to read the BUNNY INFO tab to get more information on bunnies for their health and enrichment. Also, house rabbit society has great information too for bunnies.

Hmm it does sound like gas or a GI issue. I also recommend taking him to a bunny savvy vet where they can examine him and let you know on his general health, especially since he is having issues now.

Where did you adopt him from? If it’s from another owner or a shelter then you could try asking them what Kuma’s previous diet was like and try to adjust accordingly. If you just found him randomly, the key is to introduce everything slowly. Pellets should be plain pellets without extra stuff like corn etc. If the pellets are colourful then it’s most likely harmful. Oxbow is good and I’ve also heard good things about Sherwood.

Hay should be grass hay like timothy, orchard, meadow, oaten etc. Veggies should also be introduced slowly, one type at a time and in small portions each time so you know which vegetable was the culprit if he has an upset tummy. Some bunnies are not used to vegetables and the sudden surge in this could upset their gut system. You can try stopping the vegetables for now and just put him on a pure hay and water diet to reset his system and reevaluate his diet.
