tired or affected by drugs or alcohol. Pace yourself and don’t attempt to feed an entire litter in one session. This can be a very frustrating time and if you reach the end of your tether with an uncoopera- tive animal, put it away and try another day. Assist-feeding is generally regarded as the process of placing a food item in the mouth of a snake and allowing it to swallow the item voluntarily. Force- feeding by contrast is placing the food item in the mouth and gently pushing it far enough down the throat so that regurgitation is difficult. Some snakes can be readily started using assist-feeding. Others may require repeated force-feeding before they will feed voluntarily. There are many items that are suitable for assist- or force-feeding; thawed pinky mice, mouse ‘drumsticks’, mouse or rat tails, fish, juvenile eels (elvers) and meat have all been used by various keepers. In its simplest form, assist-feeding entails gently picking up the neonate snake, placing a small pinky mouse in its mouth, putting it down again and 1. leaving it to its own devices. At this point you may need to be very still if the snake is going to swallow the food. You can usually tell pretty quickly what is going to happen. Chewing motions generally result in the food being taken, while a reluctance to bite down in conjunction with a delay of more than two or three minutes often ends in rejection. Sometimes death adders can be more definitive than that - shaking their head violently sideways, and flinging the food 20-30cm. away! Some snakes are so small when they’re born that even a newborn pinky is too large to get down. This is where long thin items of food are better; I have had great success with mouse ‘drumsticks’ and they have great food value comprising muscle, bone (for calcium) and roughage if you leave the skin on. For many small snakes the hindlimb of a small weaner mouse is ideal. It is smaller in cross section than a newborn mouse and easier to handle. Once punctured, pinky mice become limp and very difficult to manipulate in a snake’s mouth, whereas a mouse leg retains its integrity because it has a series of bones supporting it. I have found drumsticks very easy to prepare, but you will need a good pair of sharp dissecting scissors. Start by extend- ing the hind leg of the thawed mouse and pinching the skin near the foot with your forefinger and thumb. Then push the skin up the limb, much like rolling up your sleeve. You’ll find that the skin comes away relatively easily, exposing the calf and thigh muscles. Cut the leg away at the hip joint, trim of the foot and you have an entire back leg ready for assist- feeding. Of course, there will be a bend in this food item at the knee, and you should consider whether it might be better cutting the leg at the knee joint and feeding the two pieces separately.
