Hi I am new on these forums and already I want your help and advice. I've had 2 tabby cats for 11yrs and just brought in 2, 2yr olds (Ragdolls)unfortunately there's fighting hissing and growling going on. We've tried putting the newcomers in the cat carriers so that my existing cats can smell them and get used to them, and we also have let them all out. After the big fight, which I came out worst of all, they seem to have seperated themselves to upstairs and downstairs. My question is how long will it take for them to settle down and will they ever get along? I don't want to see my 11yr old babies suffer.
