Treat thief! Who is stealing the treats?

Who is the treat thief? She is chewing a treat in this photo!

Why, it's the perfectly deported Plum! Imagine.

Isn't she sweet?

 Instead of the usual cat treats, I feed them either MediCal treats or Fancy Feast dry cat food that I buy in the US. Please don't tell the cats that the Fancy Feast isn't really a treat! It's my secret.
