hi this is kenzo she is a rescue snake, she was brought into a local pet shop with a large hole in her side about six years ago, the pet shop owner knowing my interest in garters ask if i would take her, he was doubtful of her chances [so was i ] but she pulled through, the hole in her side healed but a large depression remains, because the original wound was so deep it was necessary to make sure her food was kept to small pieces this is done by feeding her mostly cat food from sachets, the type i use is whiskas which has vitamins and minerals but also no artificial flavourings i am able to cut this up into pieces much smaller than she would ordinarily swallow to allow for the damage to her stomach she has grown a fair bit since she has been with me the cat food comes in many flavours and she loves them all even the none fish variates she is easily the most placid friendly snake i have ever owned . but i have never been totally sure what type she is. i hope the photographs are good enough to do the job
