I noticed last night that there was some swelling on my cat's face, but I couldnt see any reason for it after inspecting.
Today I saw his cheek(?) looked strange, upon closer inspection I could see he'd been cleaning it and there was blood. (Pictured - looks worse in picture because his fur was wet)
He let me clean him up without meowing or trying to get away. I used cool boiled water and a cotton pad. I think I could see a small puncture wound so assume fighting.
This was 5 hours ago. He's just come downstairs for attention and it looks like he's been cleaning it again and there's a bit of blood again.
Of course I'll go to the vets if needed but I'm really hoping there's a way to help him at home?
He is still eating, drinking, going outside and wanting attention. So there's no personality change.
