It takes around 7-10 days. You can teach your kitten to respond to its name by making a sound like “mew” and having him/her come running towards you. This behavior is called positive reinforcement; it means that the response (coming towards you) makes something good happen such as petting, food or playtime. Repetition of this will make your kitten learn its name pretty quickly 🙂
Will my new kitten be comfortable with older cats / dogs?
Yes. Kittens are very social creatures and love company of their own kind so they would usually get along very well with other kittens and dogs in the household! However, if there is any aggression between them, try to separate these two groups for a while until they’re ready for each other 🙂
