We've decided to gather up the mother cat and the five kittens hanging around the house tomorrow and take them to the shelter, along with the big bag of dry cat food we still have. The kittens are old enough they are climbing up on the steps, and the mother cat has been very persistent trying to run into the house every time we open the door. I've almost tripped over them twice today trying to get out to the washer/dryer.
Mom definitely doesn't need to accidentally trip if she's going out to her car. The cats are becoming a nuisance.
