Niko has been through a lot - she was doing great her incision healed beautifully and she was gaining some weight. But then she started to have blood in her urine again and the terrible screeching sound when she had to urinate or have a bowel movement was back. So back to the vet we went. After an xray and ultrasound and the vet observing her all day she told me Niko had some very small bladder calcifications like the size of a mustard seed and a UTI as well. So we got to try a different antibiotic and for the last 2-3 days she has really gotten a lot better. But then last night after giving her antibiotic I was putting her back in her cage and she lept from my hands! And now she is wiggling around while she walks and looking side to side and almost running into things! I checked her over and cannot find any broken bones, she seems to have the use of all of her paws and legs, but is staying low to the ground when she walks. I checked her eyes and they seem to be reacting normally - any idea what this could be? I get vertigo and I know that has to do with inner ear vestibular problems, could she have knocked something around in her head should I be concerned about a concussion?
