It is important to make sure that all the conditions that may be affecting the rabbit are detected. Your veterinarian may suggest x-rays or other lab work. Fluids are administered either under the skin or in a vein along with high fiber and moisture feedings by syringe or tube. Syringe feedings can be made from ground rabbit pellets or powdered alfalfa mixed with blenderized green leafy vegetables and an oral electrolyte solution. In addition, medications to stimulate the GIT to start moving again and analgesics are used.
Some people like to use laxatives, and enzymes.
I too, have used these products in the past, but have found that they really aren't necessary. I have equal success in treating this condition with or without enzymes. Most of the cases of stomach impaction we see have been on a primary pellet diet and have had little or no access to greens or hay. They are craving fiber and fluids and the leafy greens can be just the ticket. In addition we give all these patients good quality grass hay.
