One of my ex's sister used to breed Hamsters, Russian Dwarf Blues or something and my Hoover had broken, so ex's sister loaned me her old Vax that was in her garage doing nothing, which when I got it home didn't work very well...until I found it blocked up by a few mummified Hamsters, it was hard to tell how many but there were at least eight of them.
Hamster genocide!
