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.
One of the most cold-tolerant cactuses is the green flowered hedgehog cactus (Echinocereus viridiflorus). It can tolerate temperatures as low as 20 degrees below zero Fahrenheit. The green flowered hedgehog thrives in full sun or part shade and grows to a maximum height and width of about 8 and 3 inches respectively.
