Hamster Scent Marking - Duration

[CMW328i]

Hi all,

First time posting here I think.

I have a 2 year old male syian. He's most likely suffering from chronic kidney disease according to the vet, so I'm not expecting him to live to see his 3rd birthday in a year's time.

As a planner, I'm thinking about my next hamster once he passes. I'm curious to know how long a hamster's marking scent stays around. Obviously, I wouldn't want to stress a new hamster by putting them in an environment where the old hamster's scent remains. I can replace bedding and wash certain things clean, but not everything is washable easily. For example, I have several cork logs and things that I probably don't want to get wet.

How long after he passes do you think his marking scent will remain on the items I can't clean?

Thanks in advance for any insight!
