I have two male cats, they are 9 and 6 months.
Previously when I've had cats they have stopped using the litter tray when they've gone outside. Not these cats. They are going outside then coming in just to use the litter tray then back out again.
They stink! I try clean the tray once to twice a day and they still stink! I am sick of my house smelling.
How can I encourage them to go outside like other cats?
