Gross to us, normal to them LOL
Yes I agree about the parasites, you have to be careful there.
My boofer loves it when Becker leaves cat crunchies in the tray ewwwwwwwww..
Its a rarity however, as Becker sleeps inside at night, and the tray is emptied and cleaned each day, so usually he does his buisness at night, but sometimes of course he will do one through the day.
Disgusting habit but they loveeeeeeee it
