Hi, I'm a relatively new cat owner. We have a 2-3-year-old rescue cat who has settled in very nicely, and goes out a fair bit in the day. We are keeping her inside at night, as I read this is safer for cats, as they are less likely to get run over. So far I have been doing this by locking the cat flap at about 8.00 or 9.00pm. My question is, should I be doing this earlier? If it's unsafe to let cats roam around at night - presumably because of cars - then shouldn't I be locking her in at about 5.00pm when it goes dark? But she would hate that as she's such an outdoors lover. She already tries to get out at 9.00pm, and broke the catflap by battering it once. What do others do? Thanks.
