Our kittens are now 8 months and have started going outside the last week or so when we are outside.
So far, I don't think either have even considered going outside in the dirt...
Will they just learn over time? They have only been out for an hour or so at a time so not long I guess. I sprinkled some litter in a corner area.
We aren't planning on ditching the trays indoors, but it would be nice if they start going the majority of the time outside. We have a large garden , no nearby neighbours so not encouraging them to go in others gardens.
