Yes, Tubby is an insect eater. When I lived in Green Bay I had spiders in my house and Tubby was fascinated by them. I would come home to find him staring up at the wall or ceiling where a spider was sitting. He would stay there all night if I let him, but I eventually felt sorry for him (his neck, ouch!) and knock the spider down for him. It got to the point where all I had to do was say "kitty, bugs!" and he'd come running. Then at my mom's house there are a lot of flies. He would swat them and eat them too. There aren't too many bugs around here now, but occassionally there is the stray spider. He'll get up and look at it - then watch it crawl underneath the woodwork.
