There must be something in the water here on the Ranch. Not only the radixes grow big but so do the T.s.parietalis(red-sided). My largest one, JW(female) is 40 inches and 255 grams. She has a nice attitude. She downs adult mice without any trouble. She is going to be my first T.s.p. breeder next Spring. With her size I hope she'll put out some high baby numbers.
