Mine usually lose their bottom (fangs, I think that's what you call them?) ones at the same time, and then a little later, the top ones at the same time. Just be careful where you step during those times!
Just wanted to say how glad I am to see a fellow cat lover has a cat named Mika, too. My Mika is a 1 yr old polydactyl tortie point Siamese.
I stumbled onto this forum while looking up cats losing their baby teeth. I've raised 3 cats from birth, never saw them lose any teeth. Today, my 5 mo. old Siamese kitten Fuji lost a baby tooth right on my desk. Of course, I saved it.
