Hello, I have 2 male cats that are 3 years old, they are still very playful and seem to be friendly with other cats. They live inside and outside but are inside on a night. I would like to have more cats and keep looking at local charities. I'm thinking kittens would be easier to bond with my 2 boys, can anyone please give me advice on this ? does the age of the kitten matter ? and is female or male easier for bonding. Thanks
