Before the procedure, a pair of holders (depicted in blue) should be prepared; a plastic ball can be used for this. The holes on the holders work as anchors when impression material (see below) becomes fixed.
To get clear impression of a head, inner size of the holders might be 2cm larger than a head.
The animal is lightly anesthetized by Ketamine.
Rubber tubings are placed in nose with tapes and a few drops of glue to maintain animal's respiration.
Hair is removed to prevent impression material from catching the hair.
TIPS: Hair-remove cream should be totally removed on a skin, or it will cause skin damage.
