Yeah, me and my neighbour feed the neighbourhood strays, and our favourite one had kittens about 2.5 months ago. Since they've been weaned we've been trying to catch them... we finally found their hiding place but they freaked out today when we tried to grab them. Will attempt again. So cute, but skittish.
Re: painting the helmet, I don't think you can remove the hardshell on most modern helmets, since the foam is moulded right into the shell to better prevent the shell coming off in a crash and letting the foam catch on stuff.
