Made this a little bigger than necessary to make it easier to read the specs. I really just wanna see if anyone uses this or has heard of something similar to this. My cousin lives in a ranch house with a lot of land acres. One of her cats is missing and while she will still continuously search for her baby, she does not want this to happen again. She has about 3 other cats...If anyone has any thoughts on this product please chime in! Thank you in advanced!
