We have a 10 year old feral. He lives at our house. We did a TNR on him about 10 yrs ago. He doesn't leave the yard and is fearful of everything.
He's all white, so he's sensitive to the sun. He always has burnt ear tips and now his nose is scabbed all the time. My husband has created shade areas for him.
The scab is traveling down to his mouth. It used to be just on the top portion and started in 2018 it would flare up then go away, very faint. When it went away, the hair didn't grow back. The part moving down to his mouth is recent, within the last 6 months.
We don't if he in pain, and not sure how to tell.
What tests would need to be performed and approx cost?
My husband is confident he can get him into a cage to take him to a vet. As you can see my husband can pick him up. He won't come near me. He's not mean, just scared all the time. I'm not sure how things will go once I put him in the car and take him to a vet. We are guessing it might be cancer

We'd like see if we can try medications at home. We're not adverse to purchasing medications rx or over the counter. It will be VERY hard to apply creams to his face. Pills are okay, as we can hide it in his food. We've already made the decision that we won't be spending a lot of money and will put him down if we need to start down the road of many tests.
