I've been trying to train our cat to let us put her in the carrier, in anticipation of a long car ride. She absolutely never lets us hold or handle her directly without freaking out. No purritos either. She is very food driven, so we use treats to get her into the carrier.
However, she is clever and knows that she can eat her treat outside of the carrier safely. So almost always whenever we reward her with a treat for going in the carrier, she will jump outside to chew.
We've given up on trying to get her into the front door of carriers; if you lure her with a treat she will never fully step inside, only enough to grab the treat and step out. We got a carrier with a top door, and finally got her to the point where she will sit in the carrier and wait patiently for the next treat.
However, we're stuck on the next part of training: acclimating her to closing the door. She will sit in the carrier for several minutes at a time but as soon as we touch the zipper she jumps out. No matter what we've tried over the last few months, including clicker training, she won't let us touch the door. What can we do to get past this plateau in training?
