Dry Skin

I have a 12 year old male that seems to have dry skin. Im guessing it was the last time we took him to the vet for grooming. Since then he has always seems to do this licking the air thing when we pet him near where the tale and butt meet. I really didnt think anything of it until now. He now has ripped out a patch of fur on his back and looks to be something like a scar there. He seems to lick it alot like he is trying to keep it moist. He's always been an indoor cat and always has been very healthy. I refuse to take him back to that same vet and there arent many in the area. What can I do to help his dry skin? I was told use baby oil but something just doesnt seem right about that. I really hate seeing him like this. He's my bud and I cry everytime i see it.


and one more thing..
<--- what in the world is that???? LOL

NO baby oil.....

Has he had a senior blood panel done?>

What is he eating ( brand and type

Senior what?

As for his food, its the local $1 brand. I tried him on Science Diet, and alot of others and he wont eat them. Last time He tipped the bowl and walked away. He only likes the stuff at Dollar General. I feed him the moist food occassionally because he will eat it so fast he yarps it back up.

senior blood panel ... blood work for cats over 7 or 8 ..

I would try more wet food but in small portions

Oh he had one of them done back years ago. As I said he was always healthy up until his grooming. this is a picture of him from last Christmas during the "Tree Incident"

senior blood panels Should be Yearly after age 7 or 8
