Dear friend,
Neutered males do not spray except to occasionally mark if THEY are te resident. I do not think Nigel, being the newcomer will even think about marking so you do not have to worry about that Zoie will most likely ignore Nigel so as long as he does not pester her, it should not be a problem. That leaves Oreo who sounds like a tuxedo cat. They can be quite feisty.Before you bring Nigel in.rub a damp cloth all over Zoie and Oreo and then rub it all over Nigell.Then he will have the girls scent on him. Repeat several times a day. Keep Nigel in a bedroom with the door open so the girls can check him out. Make sure he has a safe spot like under a bed to retreat to in case he gets overwhelmed.
Th odds for success are very high because Oreo will have a friend and playmate once she accepts Nigel and Zoie wil have the peace and quiet an older cat needs.
Thank you for saving Nigel.May God bless you.If you have any questions along the way, just let me know and I will always be here for you.
Sincerest best wishes,
Terri
