To all those concerned, my 12 year old cat, Tiger, had a tumor on his tail. In a matter of weeks it went from nothing to breaking out of the skin on his tail. It was formed around the nerve sheath on his spine. Pathology came back today and they didn't give a straight answer just said they had no reason to believe the tumor had metastasized and it was only mild aggressive.
Thanks for being the awesome community you guys are.
