Ack, just wanted to check if anyone had seen a tail injury like this? Molly has a lump (about a nickel-width) on the underside of her tail, about halfway down? She can still hold it up and swing it around like normal, no bruising or redness. I have no idea how she might have injured it, or what it could be from? The top of the tail feels normal. Suggestions? I can take her in to get it checked, just hate being the person who overreacts.
