Ashley, tooth decay is cavities. I'm sorry, I was only joking with you. Your rabbit won't get tooth decay from not cutting its nails. I don't think you have to worry about cutting the rabbit's nail. They live in the wild without anyone tending to their nails so the little guy should be fine. I was just joking with you about the tooth decay.
Take care, Ashley.
whats tooth decay and what can happen
Umm yeah, the rabbit's nail will grow really long and may cause tooth decay.
