UPDATE:
Yesterday Amber had a two week check up. All they did was test her urine to see if the infection is getting any better. I can't remember what, but the count of something was down, which means the infection is getting better! So she is on more antibiotics for the next two weeks to get rid of the infection completely. When they were getting the urine sample, the bladder didn't cease up and get rock hard like last time, so this is also a good sign. according to the vet.
Hopefully in two weeks her infection will be completely gone. Also in two weeks they will take another x-ray to see if the stone is shrinking at all. I think it is shrinking because she is not in and out of the cat box trying to urinate all the time.
Fingers Crossed!! But so far so good!! I will post another update in two weeks after we see what the x-ray reveals.
