I think what annoys me more is that they are so available, almost given away and sellers don’t always provide information to new owners. There is no real guidelines on the sale of some animals.
I was one of those uneducated people that bought a rabbit completely on impulse without research. I look back now and think how the store never ever tried sell me any other products. Cage, litter, food! They just handed over the rabbit (Jersey) in a cardboard box and off I went. For me, I very quickly started learning after I got her. Not ideal, I know, but we got there. I think of some of the things I potentially could have done, not knowing better, that could have endangered her life. 
I did get her vet checked early on and they gave me a booklet on how to care for her. I also I borrowed books and found sites online to learn more. Binky Bunny was critical in my education and I haven’t stopped learning since.
