Our eight month old kitten seems to be desperate to get outside, either into the garage or out the front door. We started harness training him so he could go outside on a leash.
Day 1: Harness sized for an adult cat barely fits 8 month old kitten. Velcro is no match for kitten ingenuity. Thank goodness they don't have opposable thumbs.
Day 2: Dog harness fits, and kitten cannot escape the clips. Will play fetch while harnessed. Progress!
Day 3: Outside, on the leash, digging at a shrub. Success!
Day 4: In the garage, on the leash, rolling around on the concrete. What is going on in that tangerine-sized brain? Need to replace garage door handle with a door knob. Just in case...
Day 5: Kitten lunged for the front door and got it shut on his head. No apparent damage, got to be more careful.
Day 6: Photographic proof of kitten in a dog harness, on a leash.
