My hedgehog is a little over a year old, and for a few weeks has had extremely smelly urine. Her urine has never smelled before, and though it is improving (and according to my parents is pretty much back to normal), I'm concerned. Her behavior in general concerns me because she is usually extremely friendly, and never balls up. However lately she has been acting grumpy to me and my father (whom she usually loves to death). Right now she is with my parents, as I am finishing up school, but I'm not sure if I should have them take her to a vet because I'm sometimes overly cautious. The only other odd thing about her is a tiny (like pencil point) little growth that looks like a nipple but is near her armpit area. Am I just overreacting? Could she just be acting more grumpy that normal and the smelly urine was a result of her being in heat or something? She's eating, drinking, and going to the bathroom normally. Any advice appreciated, thanks!
