How To Trap
If you’re feeding outside cats in your yard, it is strongly recommended that you get them spayed/neutered. If they are feral which means they can’t be handled, then you need to proceed with TNR (trap/neuter/return). This is the responsible thing to do as long as you’re feeding them. It will STOP them from having more kittens! Here are suggestions to follow for the PFA Clinic: I’m feeding outside cats – what can I do?
