They were worried that their ginger cat wouldn't like having a new kitten around. Then one day this happened...

"The orange tabby is named Elroy and he's three year old. The calico kitten is named Olive and she's three months old. When introduced Elroy kept hissing at her for the first couple of days, but Olive is fearless and kept trying to cuddle with him until he finally gave in. Now he's always trying to groom her (and she returns the favour by attacking him)," their human said via reddit.
