Q. I found a large amount of pee from my unfixed male cat and it had blood in it. I notice later what looked similar to crystals in the same puddle. Help

A. You should have your cat examined and a urinalysis done immediately. Some cats do form crystals in their urine which leads to bladder inflammation,look in the urine, pain and in creased frequency of urination. The specific problem with male cats is the narrow width of the urethra through which the urine passes. Make cats have a very narrow urethra unlike female cats. The crystals, blood and other "sludge" that forms in the bladder when a cat has cystitis can cause a blockage in male cats and this is an emergency. A urinalysis can determine the extent of the problem and allow your vet to recommend appropriate treatment before it becomes an emergency. Your cat should be seen today.
