I have an 12 month old cat. She has been using the cat flap for a few months now and its been great. She never wanders far from home and if i shout her she comes running in. She is also always in the garden waiting for us when we get home from work so she can have her dinner.. She hasnt come home tonight. At what point do i start panicking? I know a lot of cats like to wander and explore but she really doesn't and is never not home.at dinner time. She has found the love of Highlife cat food!
