My kittens, who are blood brother and sister, are now 6 months old and both been neutered. They go outside the catflap with ease. Love going out.
My only problem is they don't seem to understand they now need to also go outside to the toilet. I removed one of the trays and half filled it with earth and left it outside but they bypassed it, preferring to use the one indoors. I have started mixing earth with the litter with the one indoors. I bury their "no 2's" in the earth for them
All the other kittens I have ever had learned to go to the toilet outside naturally without any effort so I have never had this problem before.
Can anyone offer advice?
