Agreed that its pretty normal for a rabbit to want to atleast taste everything, and also agreeing that it can be dangerous for your bun. If he eats something he shouldnt, make sure he is eating, drinking, and pooping normally. If you notice any changes, youll want to contact the vet. It also might help if you look into bunny proofing items. I recently had to bunny proof some new phone charges since ours had been mysteriously chewed…
My Blue has eaten a ton of things he shouldnt. Hes stolen bits of my dinners (sandwiches, crackers, chips, cereal, ect) before. He likes to eat whatever im eating, even if it means lunging at me to steal a bite. When he does manage to steal a bite of my food, i always tempt him with a little more hay than normal. I will pretend to eat a bit of fresh hay and make a lot of “mmmm” noises and “this is so yummy!”. By that point, hes all over the hay like its coated in sugar
