Happy Bunno

I'm a young (questionable...) girl from Estonia. I have a pet rabbit (I really need help to identify his breed...) named Monty. My bun is two years old and he likes to explore (and yes, he is neutered). I'm also trying to get sone new knowledge about bunnies and their different behaviours. Right now my bun-bun is a little sick (snuffles) so I will take any advice on how to make him feel better.
