Rather TMI about a boy cat

[Katymac]

My cat has been licking his paws & he just started licking his nipples

I noticed a 'bit' on his nipple & gentle pulled it & took a great big bit of 'goo' out

I looked at the others & they all had the same so using a tissue I cleaned them all

Do I want to know what it was?

I'm almost sure I shouldn't have done it - but he has stopped licking them now

I have no idea what it is but I think you need to take him to the vets.

Hmm - yes maybe

but Euw

Vet says that he's fine
