Trust

Either I feed the squirrels so much the cats see them as fellow pets, or...the smell of peanuts is just too tempting!

Maybe it's the Catnip?

I bought my cats a new scratching pad. You sprinkle catnip on it to make it attractive. It is very, very attractive to Melody (in photo) and Nutmeg, who take turns not only scratching it, but sleeping on it as well!
