Hello All,

I have a one-year-old half-siamese female cat, and she's been acting
very odd lately.

It seems that her rear end (not sure exactly what though) is
sensitive, so she sits in a way not to apply pressure there.
Basically
she would sit like cats normally do on all fours, except with her
rear
end raised off the ground.

She's not eating like she used to, and she's in pain. The last time
she had these exact symptoms, she was constipated and it went away.
However, this time she excretes both feces and urine just fine.

There are no vets in the region that deal with cats and dogs - just
horses and cows and chickens and pigs.

Can anyone please advise on how to identify the problem and begin to
help her?

She lies on her back at times and asks me to rub her stomach. When I
get close to the rear end, her legs start to shake and tense up, and
she makes noises.

She's not pregnant, nor has she been spayed/neutred.

Please advise!!!
