Skight hair loss under arm

[emmab]

We noticed a few weeks back that one of our cats had some hair loss under her front leg. It is hard to see but is under her leg between the top joint of her leg and her belly, so as I said very difficult to see. Then this week we noticed the other cat has the same, in the same area. Now I am not sure if all cats have a slightly bald area here. It is not somewhere you get to see very well as it is hidden, but just curious as to what it could be. I cannot see anything there. On Gémo there may of been a small black splodge on the actual skin but just looked like pigmentation and no cuts etc. The other cat doesn't have any marks but being black did wonder if any bald spots show up more where the fur changes direction?? Just interested that's all.

I suspect it is just one of those areas that fall into a fold in the skin and naturally grows less hair. It's always worth keeping an eye on things you're not sure about, but beyond that I wouldn't worry if nothing changes.
