Cat has urniary problems.

Question
We have a three year old cat that until recently has always been healthy.
Thurs she started making frequent trips to the liter box.  We assumed she had a tummy ache.
By Sat it was clear there was something wrong with her being able to potty.
We took her to the vet Mon.  They said she had puss and blood in her urine. Along with a bunch of other technical stuff I don't understand enough to repeat.
They prescribed Hills C/D and an antibiotic.  She has been on both since yesterday.  The antibiotic is only once a day. (so she has had two doses)
My concern is since she has not been feeling well she is squatting all over.  Usually there is only a few drops of urine but it is on blankets and rugs. I am following her all over and washing washing washing.
Does this usually stop when they feel well?  Will she have behavor problems now?
Is there good prognosis of things like this?  The vet seems to think she will be fine.
How long until she starts to feel better and act normal again?
Anything you can offer would be appreciated.

Answer
HI R,
  Sounds like she is painfull. I would call your vet. back up and ask that she be put on a good pain medication with an anti-inflammatory. A new product that is great is called Metacam (a.k.a.Meloxicam)it is not approved yet, for use in cats but we use it all the time at the feline exclusive hospital I work at. I know that sounds weird but alot of medications at animal hospitals aren't approved for cats but hospitals have to use something.
  Also if she is still squatting allover the place I would ask the vet. if they would take can x-ray of the bladder too... because she could have bladder stones or even crystals in her bladder. And R, don't be afraid to call your vet and talk to them, if the veterinarian is busy then you should be able to talk to one of the assistants there. Ask questions and if you arent't satisfied get a second opinion from another animal hospital. Take care and good luck to you and you kitty.
