ki ki?

The blue jays around here are becoming more aggressive than usual.  Maybe they are nesting? Whenever the neighbor to the South’s cat Smoky is outside, they call for other birds to come and ‘mob,’ them.  K’s favorite cat is the Eastern neighbor’s cat, Ki Ki.  Not only do the jays call for mobbing with Ki Ki, but  they dive bomb him themselves.  (He often takes refuge in the budlea in our yard when this happens.) I’m not sure If K is associating the jay call with Ki Ki, or (more probably) that she is using new words for ‘cute animal’ now that she has a few more words than just ‘goggy,’ but this morning she asked to see out the window to look at Ki Ki when she heard the blue jays calling.
