Thanks, Chris. I've removed pups a lot smaller than that, but I think they have a better chance if they can get larger. Especially if they had no roots with them when removed.
I hear that about houseplants. I had so many at one point in time. You could hardly find us for all the plants. I've given away a lot of mine since getting our newest kitty this past year. He got rid of a few others for me as well.
