I only own 3 cats there's 2 in the house and 1 with me....

The one with me is behind me ....quiet like he always is....and across the yard I hear the worst mimic attempt ever ,just "meow,....meow....meow" in a human trying to sound like a cat way. I took my cat and ran inside. (BTW this took a bit cuz I live in the middle of nowhere and my open yard is at least 1 mile across)
