My youngest cat. For some unknown reason to me. likes to play in the litter trays when they haven't been used. I am hoping she might grow out of it. But she also like to make sure she kicks the litter out of the trays as well. I don't no why. Or if its just because she likes me to clean up after her I don't mind it but its got to the stage where its gettin all over the house if its not done straight away. An I went away just over night an it was even down stairs don't no how they managed it . Any advice would be really helpful.
