CONFIGURATION SETTINGS
----------------------
cacheTimeout how long should your cache file live in seconds? By default it is 21600 or 6 hours.
most sites prefer you use caching so please make sure you do!
connectionTimeout how long should I try to connect the feed provider before I give up, default is 15 seconds
showRssLinkListJS TRUE by default and will include a small block of JS in your header. If it is false the JS will not be
included. If you want the $new_window = 'true' option to use the JS then this must also be true.
Otherwise both true and simple will hardcode the target="_blank" into the new window links

Metabolic Bone Disease, or MBD for short, is common in reptiles. It is a very serious disease, and can often lead to death. MBD is often caused by lack of calcium intake, and in balance between calcium and phosphorus. MBD should not be taken lightly, and any animal that displays symptoms should be taken to a vet immediately.
