One thought I just had: If you have a cat carrier you could try and catch the cat in this. We did this once. We kept putting food in the carrier to get the cat use to going in and eating. When she started doing this on a regular basis, we covered the carrier with a towel so she couldn't see out the holes. We hid inside and watched her go in the carrier. Once she was in there my husband quietly reached over and closed the carrier door. He had to be fast cause once she started realizing what was going on, she fought like crazy. We were successful though!
