Freezing Coyote Urine to concentrate? Who has done it? Want do you use to filter it after freezing? You just freeze it till its kind of slusy and then drain off??

I concentrate all mine. Freeze in a container I then use a funnel and and tip upside down over the funnel and an other container. Keep an eye on it when all that is left is white ice throw the ice away. The good stuff I the urine thaws first you can repeat again if desire. I will useally freeze it twice makes really makes strong concentrate
