God continues to send us little angels. About three weeks ago, someone dumped a blind female catahoula and her puppy in front of our house. She was cowering in the street and the puppy was crying. Holly took them in and fed them. The female had one eye gouged out and the other destroyed. She is completely blind and is not use to it as she stumbles around. The puppy, about six weeks old, weighed about ten pounds and was sickly. She spent two days not eating or drinking and we were sure she would never grow any older. She apparently had parvo, a devastating disease for some dogs. Holly found a product called Parvaid, which we gave the little angel and within four hours she was eating and drinking. She has been eating, drinking, playing, running and gaining weight since. She had a bout with roundworms, but Holly quickly eradicated them. Three weeks after we found her, Penelope now weights 22 pounds and is a bundle of energy.

Pigeons can be a nuisance, but they are not necessarily a health hazard. The term "rats with wings" came from a 1980 play, "Stardust Memories" starring Woody Allen. Allen used the term in the movie and apparently someone with a vested interest in misleading the public decided to use it in a campaign to drum up business for pigeon control. The facts are just the opposite. Yes, there are some diseases that can be transmitted by pigeons, but no more so than any other bird, including such popular pets as parakeets, canaries, etc. Consider what some experts have said about pigeons and disease;

Snakes

Santa Fe New Mexican - July 23rd article 

One of the beneficial aspects of the recent rains has been the fact that many animals we rarely see have become more visible. Snakes are included in this group. The rains have flushed many denizens of underground burrows to the surface, including rodents and snakes that feed on rodents and inhabit their burrows. In New Mexico we have approximately forty-five species of snakes, and of that number, eight are venomous; one coral snake and seven rattlesnakes. In northern New Mexico, the most common venomous snake is the prairie rattlesnake with the western diamondback rattlesnake being found sporadically.
