Hi,

My cat Jake has small patches of his fur missing on both of his
sides.
Missing may be a bad description, I would say the fur looks thin, if
that makes sense to anyone...

I am bringing him in tomorrow morning to have the vet take a look, as
I cannot tell if this is serious or not.

Any ideas what this could be?

Allergies, thyroid, excessive grooming, nervous behavior, a number of
things. Not urgent, but I'd have him checked out soon.
