I so know how you feel :roll: one of my fosters is a right nightmare to catch - I have to try and block him in a corner. Yesterday I got a carrier out and he was inquisitive enough to jump in.
I'm also fostering a litter of babies who annoyingly run under the sofas, I have a long cardboard tube from a roll of wrapping paper that I use to very gently poke them out. Just have to be careful they dont dart straight out and under the other sofa :lol:
