That is an interesting for of art.  You would have to make sure the paint was non-toxic.  Do you have a cat?
I have two cats, I only use watercolor paint.
Watercolor can be very fun and versatile.  Have you sold any of your cats' paintings?
I just hang them up on the fridge to enjoy them myself.
There's certainly no problem with that.  What kind of cats do you have?
I have two Tabby cats.
Cute, what are their names?
I have one cat named Franklin and the other is called Thomas.
Those are very proper names for two little kitties.  Did you have a reason behind the names or find them on a male cat name list?
I enjoy when cat's have human names.
