post neuter issues!!

So both of the boys were neutered today, together. When the tech brought them out in the same carrier, they were viciously hissing and growling at each other. I bought a separate carrier for the ride home.

Now Sammy has claimed the front room (where they both usually hang) and Pippen was growled into the kitchen. They both have a bed, litterbox, water. If Pippen comes anywhere in here, Sammy growls and hisses. Pippen hisses back but runs away.

My big question is this: should I try to switch them up roomwise? Or should I let them do it themselves? I feel bad for Pips, as the front room is where I hang out too. It's the more desirable room to be. Also the tech said this is common and will go away? I'd like a little reassurance on that if anybody has any!!

Thanks!

I would keep them separated for another day or two. Then before you put them together, sprinkle both with cornstarch baby powder and rub in the coats or put a dab of vanilla extract on their noses/butts.

A few days they will be ok - its just smell of the vet's office that makes them "strange" to each other.

Do you think I should let them work the room issue out themselves (i.e. let Sammy have the run of the front room since apparently he's the alpha)? Or should I intentionally change the room arrangement?

Since its only another day or two it shouldn't matter. If it was confining for a week it would be different. Leave as is and just do the powder trick

Ok thank you!
It is pretty disturbing seeing them so nasty with each other! I hope this ends soon.
At least they are both being loving with me now. We are making progress here.

Just wanted to update the situation. Thanks for the tip to use powder and vanilla. I did that today, with cornstarch and vanilla. I had to reapply the vanilla a few times cause they kept licking it off!
Anyways, the situation has much improved! They are almost even getting along again and definitely tolerating each other. What a strange and unexpected experience.

I'm glad they are doing better today. They were probably just grumpy from going through the surgery.

Glad to see that things are working out
