My cats have been a handful lately.  Some may remember Reggie's eye
problem -- it went away for a while but is back, thankfully we have an
opthamologist in town and when they come back from vacation next week
he'll see Reggie.  So I'm optimistic about that.
 The other big problem was Simon.  He started getting really jumpy and
aggressive several months ago when everything got disrupted when my mom
was diagnosed with terminal cancer.  We ended up taking mom's cat which
didn't help matters.  It escalated into nasty alley-cat screaming
fights.  I tried Rescue Remedy and isolating the cats and lots of stuff,
but nothing worked.  I finally started using Feliway diffusers that
several of you suggested.
 So far it's worked really well!  We haven't had a single bad fight and
Simon's only hissed twice, both times very noncommittally.  I also
bought some new stuff for the cats to give them more cat-only spaces --
new cat tree, a couple of throws, and a wicker sleepy spot -- but they
haven't cottoned to any of that yet.  The Feliway seems to be the
biggest help.  Thanks!
