Although medium does not contain pigment, don't absent-mindedly imagine that it will evaporate away like turpentine. Clean it up like paint.

Cadmiums
 

Animal must love cadmiums, after days of mysterious disappearances I finally caught my little dachshound with bright red moustache...
Also another tip: if, like me, you go and buy your colours by scooter (Roman holidays style), mind to tie the bag properly when you park it, before you squash a good amount of Michael Harding expensive paints

I'm very glad that my animals don't seem to like the cads! They just steal things. Allan maybe that's how peacocks got so colorful!

Another thing to watch out for with cats....

Don't set your palette down anywhere they might walk on it! Think bright multi-colored paw prints all around and (caught red-handed!) kitty with gobs of paint caught in the soft fur between all those paw pads. The counter and window sill she walked all over was much easier to clean than all those furry paws!

Emu oil!
 

This is wonderful stuff (for skin, not to paint with). I've always fought with dry skin, especially when using pastels. Emu oil softens, repairs, and doesn't have a smelly, fruity, flowery, or unpleasant odor.

Terri, I had the same sort of cat-astrophe that you did. My bouncy little kitten ran over a large glob of prussian blue on my palette and managed to cover a lot of territory before I caught her. Aaaaaargh!
