I have a foster cat named Hushpad (I know, ridiculous name, but she came
with it) who is ten years old.  She came from a house of 8 cats, and the
caretaker was slipping into mental illness, forgetting to feed them, the
house was a mess, etc.  All the cats from that house are 7 - 10 years old
and have various health problems, haven't seen a vet in years.  One had
advanced cancer and had to be PTS.  Two have been adopted (yay!), the others
are still in foster care.  Hushpad is very small and thin, in need of dental
work, and has never been spayed.  She had a bad case of earmites, which were
treated, a URI, which is clearing up, and an ulcer on her eye that's healed,
but that eye is still squinty and is being treated.  She will only eat
canned food, possibly because of her bad teeth.  The rescue group will have
her dental and spaying done as soon as the vet clears her for surgery.

Now that I got the background out of the way, Hushpad has very small, hard,
dry stools.  I would expect that with only eating canned food, she would
have looser stool, but they are like small, hard rocks, and always look very
dry, almost petrified.  Her urine output seems normal.  I've never seen cat
poop so rock-like.  I did a cursory Google search of this group and saw some
posts about CRF.  Could this be possible?  She doesn't seem overly thirsty.
Could she be constipated?

Another question, sorry if this sounds dumb, but do cats experience
menopause?  So far, she isn't showing any signs of going into heat, I've had
her for about 2 1/2 weeks.

Thanks for your help, this girl is a real sweetie, and I hope she finds a
home quickly.
