grunting noise and teeth grinding

Today Thumper wassat next to me on the arm of the sofa and i was stroking him. I could hear a strange noise and he was grinding his teeth and making a strange noise. Should i get him checked by the vet, just worried that there is a problem with his teeth.

Teeth grinding is usually an indicator of pain. I would take him to the vets

pearl grinds her teeth when shes being fussed.. it could just be rabbit purring

There are 2 types of teeth grinding, one is a content/happy grind (equivalent of a cat purring) the other is (I believe?) much louder and an indication of a rabbit in pain. I have never heard a rabbit grinding teeth in pain so I can't tell you what it sounds like or how different it is to normal teeth grinding.

I'd give him an all-over health check and see if you can find anything out of the ordinary with him, especially around the tummy. If he is pooping and eating and peeing and drinking normally then it could just be the purring kind anything you suspect may be wrong with him and ring the vet.

Sounds like a happy relaxed bunny to me. If your bunny is always making loud teeth grinding sounds even when you are not stroken it then seek advice from a vet.

Same as above. Sounds like a happy bunny for me too.

What's the last time you check his teeth for any molar? Does your bun has a diet compose of 90% hay?

i have had him since nov and he as checked 4 weeks ago when he went to be neutered he got a check up and the vets said he was fine. Hes happy, plays loves kisses, and is always bouncing, im sure he thinks hes a dog lol, Hes never done this before, not that i have heard him but he ses to be getting closer to me, it was his first time he sat next to me and was hugging me lol, I think he was happy and i do give them aliot of hay mind you my rabbits dont seem to eat that much hay to be honest
