I took my cat Friday for a UTI, the vet pressed his bladder, took the urine off the table to test it. She said he had blood in his urine and a few crystals. She tells me she does not know how much of it is behavioral or an infection. She gave me antibiotics and tells me that even though it says dogs only cats can take the medicine too. She was quick, I was only there 20 mins, but my cat died Saturday night so if she would've gave alittle more of her time and did more than a urinalysis then maybe Hercules will still be here today!
