My 14 year old rescue cat has been with us since the beginning of December. Has two litter trays, is very settled and eats well despite having a lot of teeth out. My question is because he is a rescue cat and was with the sanctuary for five years (and possibly re homed and returned previously) when I have let him out he seems totally overwhelmed, climbing trees and racing around. I am worried he will run away in a panic. I have tried him on a harness and lead which he does not like. He is used to being indoors and I don't want him to be an indoors cat but he is crying now to go out. He won't run away will he?
