I’m a new bunny momma, and we’ve had our bun for about three weeks, he was a pet store pitty rescue. He was in a small overly warm reptile type display cage with two other buns and a bowl of pellets and a water bottle. We brought him home and have given him free choice hay 24/7, a rotating/mix of orchard grass, meadow and timothy hays, which he eats well, at least a pile the size of him or better a day. Two bowls of water that he drains regularly. We worked him onto fresh greens, of which he gets about 1 cup a day, and about a 1/4 cup of pellets twice a day (Oxbow adult). He seems young, being pet store i’m guessing about 3 months? He’s small, again, i’d guess about 1-2 lbs, and we were told he was a mini rex. I’m guessing ‘mutt’. He has a softer longer fur than the pics i’ve seen of rex rabbits. He has a stellar personality, isn’t afraid of anything, self litter trained and loves pets and his greens, and seems to have a cast iron stomach, at least for a rabbit, though we are being careful introducing new things. We have also given him the occasional small fresh fruit treat, of which he loves blueberries, strawberries and bit of banana (tiny piece). He doesn’t eat raisens, that came right back out LOL. He has his cage, and attached ex pen that is about 5×6 or so. We have just started allowing him supervised house freedom, which is enjoying immensely (i’m trying to get a good video of his crazy binky runs when he is free lol) My question is this, I know buns are not supposed to get fat, and i’ve plenty of experience with cats dogs horses ect in telling when they are too thin, just right or need a diet. How do you tell with a bunny? I can feel his ribs and backbone pretty easily, thought they aren’t sticking out or anything. He plays, binkies, runs around and seems happy and healthy, it just un nerves me that i can feel his ribs so easily? Thanks for reading my novel, i just wanted to give a through background.
