Do you have any resources on this? I've googled it for about 30 minutes and have not found much useful information on it. Can it be used on female rats?twitch said:i think its just scruffing them. there's a bit of loose skin by the neck and you pinch there and give them a lift off their feet. i don't know how well thei works though. whenever i had to show that i was the boss i just pinned them on their backs until they either stayed still or gave me a submissive lick or squeak. that has always worked for me in the past.
