I'm trapping 4 kittens and 2 teenagers right now but the kittens are more important. I only have one trap though. I am just scared that as one kitten comes in, the trap door would close on the others. These kittens always come together in a group so wherever the leader kitty goes, the other would follow at the same time. The other necessities on trapping I'm familiar with already. I was just wondering if I could use anything aside from the trap. They also wont come out unless you are far from them.
