** how to train a cat to come inside.?

Cats belong indoors, especially if not spayed/neutered. A 7 month old is still a kitten, no matter how big it is. Kittens as young as 5 or 6 months CAN go into heat. Are you ready for more kittens? Outdoor cats have a shorter lifespan than indoor cats, are you willing to risk your kitten's life? Fleas/ticks/diseases are much more common in outdoor cats & some things can spread to people. Many communities (including mine) have leash laws for cats & will pick up cats who are outside. I have both of my cats trained to use a harness & leash when we go outside, as well as being current on vaccinations & microchipped if they should get lost. I started training them when they were kittens, one is a year & a half old, the other is nearly a year old. Cats are roamers & won't stay in a backyard for long.
