at one moment i had 5, and someone just left 4 kittens near my house. and cat that i had had it's own kittens and adopted those 4 too. so for a short period of time i had 9. but i have a yard, and i am on the edge of a town (village) so they roam around. i always had an idea to put a GPS tracker on one just to see where are they going :D

Haha that would be interesting :D
