I have a white dwarf hamster about 6 months old. Now I am pedantic about diet, it's environment and I check him daily. Water replaced regularly, bedding regularly. Overall he gets the same treatment I would expect if I could not do it myself.
I picked him up this evening and noticed under his belly a sort of brownish scab that sort of protrudes out slightly. It's not like a scab that we would get from falling, instead it has sort of "grown" outwards.
There is no sign of inflammation and his hair doesn't seem to be falling out.
I am not sure what I should do? I have Aloe Vera gel but it is from the pharmacy and I do not want to apply this if it will make the hamster sick.
Also, because I play with him daily, I honestly don't know how I missed this if it was already there yesterday, unless it's possible from hurting himself (which I can't see how) as there is nothing dangerous or sharp in his cage. To me it looks a little too sketchy to be a normal scab.
Here is an image of what is happening under his stomach.
I do think perhaps a vet may not be a bad call if it does not improve. I do want to try home remedies first though if anyone knows what this might be.
