It appears the cat was very fond of you OR loved the smell of yer feet and left a surprise for you..
THAT would happen ONE TIME in my house. You are a patient man..
I do admit to not being very fond of cats. I don't hate them but they are not on my top five list of pets.
My oldest daughter has two of them AND a very, very large Alpha Male Husky who goes easily about 160 pounds on a "thin" day.. Likely closer to 200 lbs.
Good news is he likes me. But he really is huge. His back is higher than my belt and he is WIDE and LONG.
Glad he's affectionate..
