My cats mouth is "spotty" and looks strange to me. I'm concerned.

The picture comes from Reddit.com again - a good source of questions about cat appearance and behavior. The problem stated in the title is one which crops up from time to time on the Internet. It can look a little concerning because cat owners expect the inside of their cat's mouth to be pink because the mucous membrane there is normally evenly pink.

But sometimes the cells of the mucous membrane can be black because of the production of melanin which is the same pigment which colours the hair strands. It's all perfectly normal. They look a bit like freckles inside the mouth. This is not a health problem in any shape or form. Sometimes there are large blotches of black mucous membrane and sometimes you might see little dots of pigmentation along the gum line. No problem.

It is nice that the owner of this cat who posted the picture on the Reddit.com website is asking if other people are concerned about the appearance of her cat which she must love and care for well.

On a slightly different topic, it seems that the interior of his mouth is pretty healthy too! Sometimes you see some quite bad inflammation of the gums due to gum disease which in turn is due to calculus building up around the gum line.

This contains bacteria which causes the inflammation. It is very hard, as we all know, to clean a cat's teeth! That's why they end up going to the veterinarian for teeth cleaning which, you might already know, carries a health risk because they have to anaesthetise the cat and there is an approx. 1 in 400 chance of the anaesthetic damaging the cat's brain which can render them blind and even kill them (click the link above for a tragic example).
