Hello,
   I have a cat, Jonesy, that is a little over 3 years old.  He has some
ongoing problems that don't seem too serious, but they worry me.  #1.  He
always is getting "gunk" in his one eye.  He is always squinting this eye a
lot too it seems.  #2.  He has a bone cracking sound whenever he is walking.
He doesn't ever seem to be in pain though.  I mean, my bones crack if I
rotate my ankle, but it never hurts.  So I don't know whether or not to be
concerned with this.  And lastly he always acts like he's about ready to
puke something.  He'll start this hiccup like motion with his throat.  He's
not hacking like he would with a hairball.  It's almost like hiccups but he
never makes any sound.  Are any of these worth worrying about because it
seems like every time I drop $50 a the vets office, they just look at him
for 2 minutes and deem him fine.  Thanks.
