Hi, I must tell you that I agree with you in everything, or almost everything...hahaha...I loved the way you described why you decided to adopt a cat, and you have many well analyzed and accurate points.....
As for me, I have only had dogs, and it is true that I have had a lot of work regarding their personal hygiene because of the amount of hair they shed inside the house, and it is almost always a problem...but now I live with a little chihuahua and she is as neat as a cat, and she eats very little, just like a little mouse...very economical my baby...hahaha, although I wish she would eat a little more.

Best of luck with finding a suitable cat for you, they love their owners too and very much.
