Nala is 10.5 years old. For all of her life she has been an indoor/outdoor kitty. she loves to be with us and loves to be outside. This summer she was diagnosed with diabetes and she is now on shots twice a day. She is back to her old self. we tried to keep her inside 100% of this time, but she often scratches on the glass to go out. Several years ago we installed a kitty door that she loves to use to come and go as she pleases. Is it wrong to continue to let her come and go as she pleases? We feel she is happier living the way she wants. We feed her inside, she always get her shots and has a litter box inside. We live in a neighborhood with little traffic and other cats that are her friends.
