conquistador cat painting on wood

it looks to be painted on a cabinet door maybe? the paint is cracked and looks old couldn't really find any marks on either side I thought at first it might be a name going down/up his left arm looking at him but nothing else that I could find the back has to 1 X 1 inch pieces of wood(2 of them) to make it hang right I got this at a swap meet or flea market about a year ago it came out of a storage room they had bought other than that I know nothing else about it but if you can see it in the pictures who ever did it was good the shading on it is really well done. I have guests tell me it looks like his eyes follow them I can't really see it but a lot of other people have said that. he hangs in my living room above my large tv and I enjoy it.
