I adore all cats and find something unique and wonderful about every cat that I've met or been owned by. My husband says I've never met a cat I didn't love !!! But Abys I'm addicted to. (I've had 4) They have all had amazing similarities in character and temperment while also having their own personality. All the traits you mentioned have applied with one exception and SAS would agree (especially now) females don't like to share you or their territory. I'm sure there are exceptions but I personally don't know one. Zoe (RB) got on with her litter-mate brother, Maya usually gets along with her uncle Bodhi (they were born a week apart and raised together) but neither would tolerate any other cats. Rabbits , yes, but not cats .They do however stick to me like velcro, follow me everywhere and always make sure to occupy my lap. Males on the other hand love everybody... cats, rabbits, strangers.
And water... Bodhi lives in the sinks and bathtub. Maya too but not with as much passion for getting wet. And they are love bugs, burrowing under the covers to snuggle with you.
Enjoy getting to know Micah. Whatever kind of life he had before you are bringing out the happy aby traits. So only one request...yup....keep posting those pictures.
