Help needed for cat with hard stool and wheezing

I am desperate to find out what is wrong with my almost 4 year old
spayed female. She has been to the vet more than a dozen times and
they have not been able to tell me what is wrong with her. Currently
she is wheezing, has a limp occasionally, and very hard stool. The
stool is also spiral shaped. She will scoot across the carpet leaving
stripes.

She has been put on a stool softener Lactulose recently. That seemed
to help a bit but with the wheezing the vet put her on Clavamox so I
stopped the stool softener. She now has very soft stool that slips
out without her knowing it. So we stopped the Clavamox and her
wheezing is back. The vet said that she would be giving her an anti-
biotic shot this coming Monday if the wheezing came back.

Some of the vets she has seen in the past shaved her rear so the poop
would not stick and that was mostly all they did. The recent vet
clinic has done blood work and x-rays with nothing found. We have put
Flamazine cream on her rear as well as Hibitane cream. The cat is not
getting better but worse. Does anybody have any ideas as to what is
wrong with my cat?
