Considerations. The most common organisms in the normal bacterial flora that inhabits the large intestine are anaerobes (Bacteroides, gram-positive rods, and gram-positive cocci), gram-negative enteric organisms, and Enterococcus faecalis. Using differential selective media and enrichment cultures, normal flora can be differentiated.
Rabbits by nature are cold weather animals. They can easily tolerate temperatures at 32 degrees Fahrenheit or lower providing they have shelter from the wind and wet conditions. They have trouble tolerating temperatures above 85 degrees Fahrenheit and must be kept out of direct sun light during the summer months.
A Bird's Metabolism. Parakeets and cockatiels maintain warmer body temperatures than humans do. Their normal body temperatures run between 102 and 112 degrees Fahrenheit -- they chill faster when the room is cold or the temperature drops. A pet bird has to work to maintain his body temperature.
