Hey guys- I believe my female cat has a UTI anyway I can make her more comfortable today?

Hey guys! I have two pretty important questions here that I’m not getting a full answer by googling so I figure I’d see if anyone has some knowledge

I noticed my cat (6yrs) acting differently this morning, nothing I can really describe, just different. I would say she almost seems uncomfortable but she’s more or less acting perfectly fine. So I watched her closely and noticed she tried to pee like 3 times in 5 minutes, and when looking at the drops of pee it obviously had a shade of pink to it. Other than that she’s playful, drinking water, getting zoomies, and eating. I called my vet, of course closed today, left a voicemail and also left a voicemail with my emergency vet.

My question is, what can I do today to make her more comfortable? I read that giving her canned food instead of dry food can help make urine less concentrated but was worried about changing her good.

My second question is: this is the second UTI she’s had in 1.5-2 years. I keep her litter clean and have a water fountain that I clean regularly. Any ideas? Thanks for your time
