Teat Infusion Canulas. There are many uses for canula tips. Most Wildlife Rehabilitators use them for birds and mammals. They are very helpful in treating adult animals with medications and liquid diets. These canula's will fit a luer lock or a slip tip syringe. We do recommend using a luer lock in most cases therefore the animal will not have the chance of ingesting the canula. These are available in a box of 100 or by the individual canula.
