At 16 months old, My Granddaughter Lily, is really interested in kitties for short periods of time. She likes to crawl after them. Kittens are usually pretty smart with toddlers, & are able to keep one step ahead of them.
Elijah, my nephew, at age 7, didn't care to sit still any longer than the kittens. Children this age still need some supervision with a pet, but can help care for them.
Kind, older children, are the perfect pet care givers.
A pet provides companionship & teaches responsibility.
At age 2, Lily was well behaved with this puppy. 2 year olds should not be left alone with puppies.
Pups & kittens have their own ways of getting to know each other.
