Perry is SIX YEARS OLD and STILL doesn't get it! She has gotten to where she'll usually grab the head to kill the rat but then she searches the whole body for the head againone time (a month ago) she grabbed the live rat and threw it and herself into the water and half suffocsted half drowned the thing. Then she kept her head submerged while eating it, coming up for air periodically and then exhaling underwater. I really thought she was going to drown herself! Mind you she has also eaten it backwards once and i thought she was going to break her jaw! She pushes the rats into her mouth with her body or anything else she can, but she isn't above slinging it around when it's half down her throat to get a better angle to push with... idk she is my special girl. Draco my year and a half year old will grab anywhere to kill but always has found the head and just remains coiled around it until it's down. So sometimes they outgrow their crazy eating habits, but not always obviously.
