As the young snake grows, it can be stepped up to taking mouse fuzzies. I have found it better for the snake to feed on one larger prey item rather than several smaller ones. I prefer feeding one fuzzy instead of two or three pinkies, and have found that the snakes grow quicker with this method. Once the snake is able to take small to medium-sized mice, one feeding every 7-10 days is adequate, and one feeding every 14 days will suffice for adults. Most adult sand boas can take adult mice or weaner rats. The ideal prey size is just slightly bigger around than the girth of the snake.
Occasionally, sand boas stop accepting food, or, in the case of newborns, never even start to feed. Following are a few tips to help get problem sand boas to take food The first and foremost reason that juvenile and newly acquired Telephone Number List snakes do not feed is unsuitable habitat -- enclosure size, substrate, hiding areas, heating, etc. Double-check to make sure conditions are correct. The prey item may be the wrong size. Sand boas even sometimes refuse food that is too small. They usually readily accept prey that is about as big around as they are at the thickest point. Try feeding larger food items rather than smaller ones; this has worked for me particularly with rough-scaled sand boas.
Prey species also makes a difference. Some individuals may prefer mice to rats, or vice versa. Try varying food items, including mice, rats, hamsters, gerbils, chicks or small birds, and small lizards such as Sceloporus or Anolis. o If all else fails, my next step would be to "dry the snake out." Remove the water bowl and turn up the temperature a degree or two. After a week, offer a dripping wet prey item, touching it to the snake's mouth. Often the snake will drink from the food, and then proceed to eat it. This method has worked several times for me with rough-scaled sand boas and Russian sand boas.
