Well today was my first attempt at F/T.. I fed 2 out of 3 of my balls (1 is in shed), my yearling Gopher snake and my Kingsnake i got when i was 8 years old and i'm 37 now.. None of which had had F/T before today. 4 out of 5 of my snakes took them. What i did was i Googled "how to feed a snake a frozen mouse" and it went to this link http://www.wikihow.com/Feed-a-Snake-Frozen-Food.. I followed the steps on the site and watched the youtube video at the end of the steps. The video is very helpful.. I did exactly what the steps and video said and it was a success. Until today my 29 year old kingsnake has always taken live mice i wasn't sure he would even give a F/T a chance...
