We have 2 cats who are 4 years old. They have always been inside cats but we have a large pen in the garden that we put them in when its nice so they get fresh air.
We are wanting to start letting them out as one in particular always makes a dash for the door and I think they would enjoy exploring outside.
What's the best way of introducing them to the outside world? We are thinking of letting them out before breakfast one day so they in theory should come back but what else can we do?
