Spooky is a pretty small, slim kitty. She is a garden buddy as well and has learned not to attack and fatally beat the plants, as was her practice early on. Here is a photo I took of her shortly after she arrived last Halloween season, and another picture with her big brother, Bear, whom she loves dearly. Bear was a stray that I found on the side of the road 3 years ago next month.

Spooky is just a smaller version of Squire Tom. Mine do the mouth thing too...It's a nurturing thing that mama dogs do IIRC. The other evening they were rolling on the carpet, doing the mouthing thing. Tom jumped up, pulled Rascals tail, hid under the couch to look and see if she was following him....They bring such joy!
We keep catnip growing by the front door for Tom...He leaves it alone unless we crush some of it....Then he helps trim it back or rolls in it.
