My two rescue cats have recently started going outside. So far so good, they mostly stuck to the back garden and the gardens that back onto ours. However, this week they have learnt to jump over the side gate and get out the front. We live at the end of a v.quiet cul de sac so no worries about cars, but my male cat came home with a big scratch the other day, and this morning I saw him crouched down having a stand-off with a cat who lives a few doors down. I tried to call him in but he wouldn't come, so I went out and picked him up and brought him in. The other cat sauntered off. Should I have just left him to it? He's my PFB and I don't want him to get hurt!!
