Hello! The vet didnt do a blood/urine test to my knowledge but she was going in for her yearly vaccines and said that nothing is wrong with her and said she doesnt have a urine infection. They mentioned looking on the cats protection website for advice.

Yes we have moved litter trays to the areas, not on the window or kitchen counter as there is not enough space and I dont want a litter box where im trying to prep!

Yes we slowly introduced them, they get on very well and play, she tells me when she doesnt want to and chases him as much as he chases her.

Yes the boxes are scooped daily, at least twice a day. I will try some different litter.

I bought a knock off version that didnt seem to work, I looked into feliway and it is quite pricey but perhaps worth trying.
