It takes 4-6 weeks for the hormones to die down. It's good that you are taking it slowly. Have you tried swapping the litter trays around?
Good luck! :wave:

6 weeks is the ideal time according to my vet, 4 weeks maybe but I think it's safer to wait out the 6 weeks. In the meantime, you can do what antigone suggested and swap their trays/toys/etc around so they get used to each other's scent.
