The ONLY 3 things possible that clean cats (or dogs) teeth is brushing the teeth with a toothbrush and special toothpaste, feeding them raw meaty bones or going to the vet and putting them under to clean the teeth. Also, dry food is linked to other health problems such as obesity, diabetes, UTI's, renal failure, etc. The negatives of dry food really outweigh the positive. I do not feed any dry food to my cats after doing much, much research. I am not sure how amoxicillin will get rid of anything if they said no infection was found. Amoxicillin is an antibiotics specifically for infection. If you are able, could you take her to another vet for a second opinion? I probably wouldn't let them do another urinalysis as that is rather stressful for the cat. You'll want to feed a higher quality wet food as Pro Plan is a lower quality and I'll point out why. Also, the Urinary form of the food only comes in 1 flavor and I promise you your cat will get sick of that same 1 flavor day in and day out very soon. Here are Pro Plan Urinary Tract Health Formula canned food ingredients: Water sufficient for processing, meat by-products, chicken, wheat gluten, corn starch-modified, natural and artificial flavors, soy flour, potassium chloride, taurine, tricalcium phosphate, salt, caramel color, Vitamin E supplement, thiamine mononitrate (Vitamin B-1), Vitamin A supplement, ferrous sulfate, zinc sulfate, manganese sulfate, pyridoxine hydrochloride (Vitamin B-6), niacin, calcium pantothenate, riboflavin supplement (Vitamin B-2), copper sulfate, Vitamin D-3 supplement, Vitamin B-12 supplement, menadione sodium bisulfite complex (source of Vitamin K activity), folic acid, cobalt carbonate, potassium iodide, biotin. B-4664 By products are parts of the animal not deemed for human consumption. As you can see, they don't even mention what animal, it just says meat. That could be anything. By products normally consist of feathers, beaks, head, feet, diseased meats. Wheat gluten is the cause for thousands of loved pets dying or becoming very unhealthy back in the 2007 mass recall of pet food. Soy flour is unnecessary. Salt is unnecessary. Any coloring is unnecessary. You will want to feed canned foods that do not contain by products, corn (maize, same thing as corn), soy, coloring, salt, sugar, gluten of any kind. You will also want a canned food that has a meat as the first or second ingredient, first is more favorable. High quality canned includes AvoDerm Select Cuts, Blue Buffalo, Natural Balance, Wellness, Weruva, Evo, Merricks, Wysong, Newman's Own, Petsmart's Authority and there are others. These in general are more expensive but you will end up saving as, since you'll be feeding higher quality food, you won't have anymore expensive vet trips."
