one of my boys is often sick .. because he eats too much too quickly!
I think we've about covered the "joys" of being owned by cats, what with live things, dead things, internal & external parasites, digestive issues
... just two other things - the knack of getting under your feet (the number of bruises I have, trying NOT to step on a cat and getting bashed in the process!!)
when there's 4, there's usually one in a daft place here!
Secondly, the knack they have of Knowing if a person doesn't like, is allergic or cannot see cats!
My little monster is totally in love with a friend who is very allergic, he taps her with his paws and she comes up in hives if his claws touch her
He is a b*gger for getting in her car (she should pay more attention & not stand gossiping with the door open!) and spreding his cat-ness everywhere too!
