An Egyptian Mau cat costs between  100 and 200 dollars, if you are looking for great bloodlines, however you can get cheaper ones with basic bloodlines for free if you place ads around looking for a mau.
Definition of guano. : a fertilizer containing the accumulated excrement of seabirds or bats; broadly : excrement especially of seabirds or bats.
The odor also attracts arthropods which may later invade other areas of a building. Bat guano may provide a growth medium for microorganisms, some of which are pathogenic (histoplasmosis, for example) to humans. Guano accumulations may fill spaces between walls, floors, and ceilings. It may create a safety hazard on floors, steps, and ladders, and may even collapse ceilings.
