Hi There,

Hissing is very normal whenever a new kitty is brought into a home. Luna is letting the newcomer know that she is not pleased, and that he is in her territory. It's best to keep your new boy in his own room for a couple of weeks. This will give them more time to get used to each other's smells before they actually meet. All introductions should be slow and gradual.

Please be sure to use an enzymatic cleaner to clean the bathtub. Otherwise, the odor is likely to remain and the tub may well be used as a litterbox again.

Hope to see you in chats this week

Regards,
PHKitkat
