Pet's info: Cat | Mixed Breed | Female | spayed
Hello my cats have always gotten along with each other. I have 3 females one male and I also foster cats. They were fine with the foster cats coming and going until recently, my male main coon (3yrs) started attacking one of my female tabby (2years) causing her to spray all over the house. We have tried boar mate spray encase it was sexual agression, calming spray, calming drops in water, and calming pheromone collars. How can we stop the peeing!

That is concerning! As with any sudden change in behavior, it's a good idea to schedule a veterinary checkup for all of yours cats. In some cases, aging related issues such as pain or arthritis may cause a cat to become more aggressive in an attempt to protect itself, or it may start getting picked on by other cats in the household.
In the meantime, making sure all three cats have easy access to food, water, litter, places to hide and rest, etc can help create zones where they can relax without starting a fight over these resources. Adding in a pheromone diffuser such as Feliway to shared spaces (such as eating or sleeping areas) can also help reduce inter-cat aggression.
