I cannot tell you how true that is! I now only have 2 cats. My 2nd cat Mary (I call her autistic Mary because there is something just wrong with her. I describe her the way most mothers do when they have an autistic child, but just can't pinpoint their finger on it (nor can the doctors until the child is older). However, ANY LITTLE noise, distractiom, inside ot out, she's on in 2 seconds.
When my place was under construction I had a mice problem. I had NO idea what a huntress she was. When there aren't mice it's moths, bugs, anything that moves and does not belong there.
My 2nd one Mimi is just a big fat fatty who lays around and comes to me when he wants affection. He just watches Mary the huntress do her thing.
My dogs kill bugs. One of my dogs, who is 120 pounds, whacked a fly to the deck with his paw. It was dead before it landed. Inside the house, they snap and swallow moths and flies out of the air.
Sorry about autistic Mary. Was she a feral cat brought into your home? My little black cat was a feral kitten and those type of cats never become domesticated. She’s staring at me right now - as if I was a nice piece of steak.
