Several weeks ago I was asked to foster a singleton. A little kitten found on the side of the road. A hitchhiker's name seemed appropriate, so I named him Arthur Dent.
He was underweight, about a week behind in growth, and had copious amounts of diarrhea. Like "where on earth did you store all that" diarrhea.
But he was a sweetheart
As most single kittens are want to do, he treated me like a sibling. While we did a lot of cuddling, he could not help himself when it came to play. He wanted to bite and wrestle with me constantly. He was much more persistent in this than the kittens I've dealt with in the past, save for Edgar the Obnoxious. After a while it was easier to snuggle him and he was less likely to put aggressive play when it was clear I wasn't interested
I would redirect Arthur Dent to a sock monkey I had in the kitten room that was about his size that I named Zaphod. He enjoyed beating him up and bunny kicking Zaphod silly.
Arthur's diarrhea eventually cleared up and he continued to thrive and made weight. He was still a little small for his age, so despite only being two pounds, I was comfortable sending him back to be adopted
