For some reason my three year old female, Tribble, smells like... well, beef bullion, and she never has before. At first whiff I almost thought it smelled like gardenia, but I had my mother smell her and she said beef bullion, upon smelling her again, I agreed. She doesn't have any sores or anything, her temperament and activity hasn't changed, and no, she hasn't been eating beef bullion or any meat. I don't think it's her diet as it hasn't been changed in a long time. She eats Oxbow Chinchilla Deluxe along with Oxbow timothy hay. Her treats are rolled organic oats and occasionally a dash of a mix of organic nettle leaf, oat straw and dandelion leaf. Any clue what's going on? Is she in heat or something?
