The fossil record for bacteria is not especially good (!).  Whole clades of
bacteria may have gone extinct at the K/T, and we'd never know.  

As for the other groups you list, subsets of many of these groups (e.g.
birds, as Mike pointed out) did go extinct.

Your beloved pets dont have to hunt their own prey, I would imagine.  Or at
least I hope they don't - for the sake of the native fauna.
