Hmm...
The way our trap is built, it should be possible to tie a piece of fishing line to the trip-arm, so that you can manually yank the "trigger" when the cat enters the trap. I don't know what kind you're using, but it'd probably be possible, if you examine the mechanism.
Yes...I tried that too(with string), but then my pole broke and I was unprepared to go any further since it was late already. So yesterday, I had to buy a taller ladder, and used the bigger dependable trap I had and the cat almost went in. I left everything out there with trap tied open and food and water inside, and will try again tonight. This is a 15 mile one way drive for me. So, i’m going back after work tonight and will hope to God it goes in this time. Meanwhile, from teh roof area, I see 4 week old kittens poppping out from under a hedge over there. I have to get them now too....unbelievable.
