First of all I will admit I am one of the most paranoid, worry-prone cat mommys around. I just had an uncomfortable thought....

Bo is away having radioiodine to cure his hyperthyroidism. He will probably need to be gone until the 29th, the facility I took him to likes to release without any handling restrictions (radioactivity), so that is why he needs to be there so long. It will be about 11 days total he will be gone.

What if my other cats don't remember him when he returns? What if they hiss and fight?

Hanna, Abby and Bo usually get along so well, they have never had any fights or skirmishes. I know Bo will smell funny to the other cats when he comes home. None of my cats have ever been separated so long from each other before, overnight is the longest.

If you have multiple cats and have had one leave for a week or two, what has your experience been when the cat returns?

Can anyone help ease my mind?
Or am I getting all worried for nothing?
