Last night our hamster was scrambling all over his cage while E was feeding and petting him. The cat monitored every last movement. Once the cage was closed, the cat climbed up on top of the hamster cage and crouched there, trying to push aside the pillowcase we keep on the lid of the cage, so he could watch the hamster directly. (Unfortunately for the cat, the pillowcase was pinned in place.)
As the cat crouched, straining to monitor movement down below, E reached up from behind him and quickly touched his tail. The cat instantly spun around. “What was that? Who touched my tail? Has that rodent figured out how to get out of the cage and he’s up here where I could get him after all?”
As the cat intently scrutinized that side of the cage top, looking for the hamster, E again reached up unseen behind him and touched his tail. He spun around again, looking even more vexed at the idea that the rodent was up here somewhere messing with his tail, but he just couldn’t find it.
E tapped his tail a couple more times, before we decided the cat had gotten enough stimulation for one day and we were out of breath from laughing so hard. The cat never did figure out exactly what happened.
