That sounds like an excellent plan, Sir or Madam.
None of our cats were ever allowed outside alone for any reason.
After years of being indoors, they usually have no desire to see the great outdoors up close and personal.
My late Rocket was the only guy who wanted to go out, and I would take him for walks around the yard,
never more than 3’ away from me. He chased chipmunks, ate grass, and threatened to go out on the road
(but never did it). When he was done, he would lead me over to the man door of the garage and stare at the
doorknob until I let him in. Then when I opened the inside door to the house, he would streak in there and
brag to the other cats about his adventures.
I really miss that guy. He died of CRF on August 4, 2012, when he was 17. He lived with us for 15 years.
Whiskers is an outside cat because some family members have allergies. He was a stray (which I adopted and fixed) and has always been outside. We live in a gated community so the majority of people drive slow. I still worry for him, but I think he’ll be okay. No predators that I am aware of.
