We had a set of kittens given to us by a family member because they wouldn't survive the environment they were born into. One of them, we called Bigfoot, because he had these big honking loafers for feet. Of the three, he was the fattest, but also the most loving. Always taking up the opportunity to snuggle with whomever he could. Eventually, once they were big enough, we had to put them all outside. He adjusted rather quickly. But the past few days he had been crying out quite a bit and we didn't pay mind to it. Come today, he wasn't crying anymore and his belly was the far opposite of what it was before. Sure enough, I did some research and we figured out that he was dying. We don't know what caused it but it was set in stone. We put him in a box with a fluffy towel and comforted him in his last moments. Goodbye, Bigfoot. We're gonna miss you, ya big lug.
