When I was younger I had this cat I called Queen Bee. I had to help my mom and dad move to different houses and I brought her with to my dad's house that had a couple barns, the house, a old tool shed, a hay shed, chicken coop and a large brush pile.
Queen gave birth to a litter of kittens two months before the snow of winter. I noticed that a week or two into the winter the old tool shed, that she had her kittens in and claimed as hers, had a several large fur nests in it that matched Queen's fur colors. I watched as she came in and curled up in one of the several nests and her kittens in the others and all of them had lost the tips of their ears to what I think was very bad frostbite. But what I'm confused about is that the tool shed was the warmest place on the property other than the house and the hay shed.
And also Queen was probably around 9 or 10 years old, so she would know better than to be outside in the cold long enough to get frostbite. And she had kittens litters before and they all were great well taught to be good cats.
So what happened to make her and her whole litter lose their ear tips to frostbite?
