Scat #922702

Asked December 06, 2025, 4:03 PM EST

I am trying to find out what ermine and weasel Scat looks like. I have a critter in my house and I’m trying to figure out what it is. At the same time the mice are gone so I believe it’s one of the two above.

Hello Carol,

Thank you  for reaching out to the UNH Extension Infoline.  This UNH extension site describes weasels (ermines) :https://extension.unh.edu/blog/2018/02/looking-weasels

They are carnivores.

The following site has information and pictures of Weasel (ermine) poop or scat: https://wildlifeillinois.org/identify-wildlife/least-weasel/#:~:text=the%20front%20tracks.-,Scat,Behavior%20&%20Ecological%20Role

The following site does list a lot of small critters that could be  your issue however it does not distinguish their scat: https://www.extension.purdue.edu/extmedia/fnr/fnr-413-w.pdf

I don't know if you have chickens that are being attacked but the following site lists many small animals that  are carnivores :https://extension.okstate.edu/fact-sheets/protecting-small-poultry-flocks-from-predators.html  The following site has pictures of their scat: https://www.wildlifetrusts.org/wildlife/how-identify/identify-poo

I hope this information is helpful!  Please feel free to reach out with any further questions!
