And could have used some of these ideas.
We have a range of reactions - Maya is friendly and calm until she is held. My husband cornered her in the cat door to the porch (we have 10" thick walls and cat flaps on both sides so that makes a cat sized alcove. Usually she is good about not using claws and teeth but she got him a couple of times. It took about forty five minutes to get her into her carrier.
Sabra hides under furniture so we had a good half hour getting out from under a bed and a nightstand. Fortunately she goes passive though she growled and hissed at us while we were getting her out. That was about a half hour of excitement.
Lucas is the easiest - he was at the door of the bedroom where he and Sabra had hidden, so I caught him as he tried to come out the door. His carrier has front and top doors so he was dropped in the top.
So it was over an hour to catch three cats that were just going into the vet's for booster shots. That, even though after their last trip to the vet three weeks ago, two of the cats would go into their carriers here at home to hang out.
I think in a few months I will bring the carriers down from the attic and we will give them their once a week canned food treats in the carriers. That will give them time to forget yesterday and give us time to prepare them for their vet visit next year.
