A little over 3 weeks ago I noticed my 1.5 year old female cat(Mia) straining in the litter box and not producing a lot of urine with some blood. Took her to the vet and got meds(antibiotic and cosequin) for 2 weeks with a follow up appointment. The vet wasn't able to get any urine at the first visit for a urinalysis but did get a urinalysis done when we went back at the 2 weeks appointment. The vet described her urinalysis as A+. Ph was 6.0 and no crystals. Now a little over a week later I started to see a little bit of blood again and a decrease in urine output. When I noticed this last night I went ahead and gave Mia a dose of her antibiotics. The vet had wanted me to get Hills C/D + stress only because I have a multicat household literally that was the only reasoning. I understand stress is like the number one reason for urinary problems. I've debated about the perscription food because I know that it is filled with crap. I've been doing a ton of research on everything uti related. I had decided to imorg. ment diet changes(low carb, low phosphorus, more wet food, more water, no fish) from information I gained from catinfo.org. I already feed my cats wet so I have been trying to increase that amount and cut way back on the dry(which I'm also transitioning to Purina One Urinary Health) Everything is moving very slowly so Mia doesn't get even more stressed with food changes. We have been trying new wet foods in between their regular friskies trying to move towards the low carb/low phosphorus but the cats are being very picky and all of them have only liked one kind so far. As for the decision to try the purina one I thougjt of it as more of a procaution because they have always had dry food so I can't just quite giving it to them and the vets only reasoning for perscription was due to the fact we are a multicat household. Now though with seeing blood in Mia's urine again I'm second guessing myself and wondering if I shouldn't get the perscription food atleast for the time being. I bought fountains to replace the water bowls right after this happened and all the cats gave adjusted to them and now really love them. I am using only filtered by reverse osmosis water in them and I add water to their wet food. I'm going to call the vets office to see what they say about whats going on and if I need to bring Mia in or to just continue giving her the antibiotics for now. Any help would be greatly appriciated.
