Loved watching the cats we had stalk spiders, especially when they were relatively high on the wall. The mighty smudge would leap up and knock it down and then it was a race which of the three got it first. Worst thing... When they start stalking something under the sofa you are sitting in. Often found legs near the skirting boards. Snoopy preferred moths and would sit for ages waiting for them to fly into their run. Sometimes I was naughty and put a lamp out there.
