I think cats are misunderstood, a lot of people think they play and are loving.
Far from it, they are training to hunt and bonding as a pack with you. They are wonderful animals, great hunters and that's why they are so dangerous.
Tap on the side of your fish tank, are they coming to say hello? come on. ...they think you have food.
In nature there are harmonious inter species relationships, dog and man is one, crabs and fish, cleaner wrasse etc. NOT CAT AND MAN!!
Give me the song of a bell bird, rather then picking up neighbors ******* cat crap from my vegetable garden.
