Joey is an orange tabby who has chased male cats larger than himself out of the yard and at least once backed off a raccoon. Yet twice now when we’ve been doing kitten foster, when one of the kittens escaped from the bedroom and Joey saw it, his eyes got big and he ran the other way in terror.
I have no explanation.
He also enjoys eating plastic baggies and yowling at 4:30 am for no apparent reason. (And he is also very smart, hugely curious, and utterly loyal to me. A great, if sometimes puzzling cat, with personality. It’s never boring being around him!)
