Cat's Tail Playing Phase?

[macyaji]

When my two cats were little, they love to chase and play with each other's tail. My younger 5 month old kitten TJ grew out of this phase, however my 1 year old cat Rose still very much love to play and chase TJ's tail. Is this something I should worry about?

No, I wouldn't worry. If it annoys your cat enough they will let the other know.

They sound like they have a great relationship still. TJ will let Rose know if he objects!
