I noticed that one of my cats has a raw section of his nose, on the leather section. It appeared after a night where the two cats I have got into hissing/low growling during 'play'.
The cat is acting normal and doesn't seem to be in pain, but we cannot figure out what could have caused it since it does not look like a scratch, and it covers about 1/3 of his nose.
Is there any special considerations I should take to ensure that his nose doesn't get infected, or is this something that requires a vet visit?
