Our two cats are almost 1 and we've had them for 4 months. We've just started to let them out during the day now that they are vaccinated and fully recovered from their spay/neuter. At night I call them in and lock the car flap but they sit on the mat asking to go out. DH and DS2 both say it's not fair to shut them in and I and DS1 prefer them to be safely indoors at night. We can't cat proof the garden because it's too big and there is a five bar gate out of the drive which they can just jump over/under/through. What do you all do? In or out?
