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.
Generally speaking, 65-80 degrees Fahrenheit with 75-85 percent humidity is the ideal temperature range for growth and reproduction of fleas. All they need is a warm place in which to settle and lay their eggs. For the majority of pet owners who keep their homes at a consistently warm temperature throughout the winter season, this can mean that a flea population, once settled indoors, can remain active all year long.
