I have twice been given more treasure room for a pet that is not the active pet. Is this usual?

PS I did a search and couldn't find any information so apologize if asked already and I didn't find it.

I'm pretty sure that event hits a random pet. I don't think it's ever actually hit my active pet, to be honest. :P

I believe it can happen to any pet. some of my pets that aren't active have gotten that event.

Good to know amd it must be just pure coincidence only one pet has ever received any and that is my original, which is why I was wondering if the game was programmed that way.
