Kibble in the water bowl?
Years ago, I had a neutered male cat, Bob. He was a great cat. Dog people often said he was more like a dog, and he lived to be 19 years old.
He had one peculiar behavior - not a problem, just kind of a head scratcher. Every morning, when I gave him his food and water, he would very deliberately take one kibble and put it in his water bowl.
Anyone else have a cat who does this? What was the idea, I wonder?
