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.
Remember that bat droppings (guano) will accumulate beneath the bat house; this is another good reason to select a somewhat remote location, where the presenceâparticularly the smellâof guano won't be bothersome. You can periodically scoop away guano and add it to a compost pile or use it as a fertilizer for plants.
