I had a cat who looked pregnant because of her avocado diet (nice coat though!). She'd hunt avos from the neighbor's tree, bring them home hanging from her her teeth by a sliver of peel. She'd park in a corner and peel the peels off in tiny tiny bits that would dry up and look like some kind of rodent dropping.

She'd eat the yummy part, and then chase the pit all around the house.

Silly Sadie Cat.
