I DO NOT recommend this in any way but....we had a femail cat dropped off (we have a nice big red barn) you could tell immediately that she had a urinary problem just by watching her. Probably why she was dropped off. We had a choice, put her down or take to vet...NOW I no way wanted a cat in the first place. I told my DH I had some cipro and to grind one up and put 1/4 in her food, you guessed it he was feeding her. She got better immediately....dancing and prancing and chasing her tail etc. Works for me and did for her. I know your not suppose to give aspirin to animals but it was either let her suffer and die or take her to the vet which I didn't want to do. The animal shelter would have put her down immediately. Like I said this IS NOT a recommendation just what I did LOL
