How many boxes do you have? You should have one per cat plus one OR if you have multiple floors, one per floor of your home.
For food, you can get Urinary cat food at the store that's a little less expensive. I use Purina urinary wet. There's also a Purina urinary dry.it's purified drinking water. But hopefully if its allowed I feed her rx and wet food because I have so much wet food . She may have to be on rx if I want to avoid vet visits
It depends what country you are in. Usually the alternatives to clay last a bit longer than any litter so it was more money upfront but you don't spend it as often.
If your cat doesn't have stones, the RX shouldn't be necessary. The RX is for dissolving stones. Once a year has passed on RX, most cats can maintain on the "over the counter" urinary diets as they are lower in phosphorus and magnesium and such that cause stones, so new stones don't form.
That depends: did the vet tell you she has stones? Or is it reoccurring infection?
Yes the Purina has citric acid to raise the PH level of the urine.
I suppose that depends on who you ask and their views on what is healthy for cats.
