My little black cat Gina has had a UTI, which is gone now, and crystals, which are still in her urine. I have switched her to Nutro Max (I had a free sample of their indoor formula also and she ate it all, she loves it) also I am giving her cranberry extract, she likes that too. When we went for a check, the vet gave me anti-inflammatory pills to give her. Do you think this will help? She is licking down there but using the litter box as usual. Is it worth the ordeal of making her take the pills?
