The doctor of my local veterinary clinic called to give her condolences, and the topic of giving Smith an ultrasound came up. His brother had an enlarged heart, problems with the right ventricle and the left atrium, so for safety’s sake, an ultrasound for his brother Smith should be scheduled. The doctor then told me something that I had not heard of before…
“Smith and Weston looks so different, and it’s actually quite common for kittens of the same litter to have different fathers.” So Smith may not have the congenital defects that Weston had, and it could explain their very different temperaments.
Being the fact checker I am, I looked it up on the net, and sure enough, I find information confirming the incredibly prolific and efficient reproductive nature of cats:
