I noticed this on one of my rats bellies this morning. He does not seem in pain however I have noticed him cleaning the area frequently. I have separated him as his brother until I figure out what this is, what caused it, and how I can make it better.
Any advice is much appreciated!

@Loren Hagerman oh my....that's what my boys tumor started out looking like! It became almost the size of him within a matter of weeks! By personal experience, the only way to know what it could possibly be, is taking him to a vet. Some regular vets don't even know. Best of luck!
