Introducing 2 new cats should be a slow and gradual process... Luckily we had it easy with Cole and Marmalade and after 5 days they were living in the same "territory" and getting along well.
This video shows how we introduced them, but there are many more methods and tips in the links below.... GOOD LUCK! :)
