Thank you all,
@HarryBeau,
@trick60 ,
@PenguinMum , and everyone who sent prayers, purrs, positive thoughts, crossed everything, best wishes, and hugs for the KittenCat. We are back from the vet, who said she was not worried about the bald patch. She thinks maybe something bit the KittenCat or she got scraped, and started licking the irritated spot, wearing the fur off. The KittenCat was fitted with an E-collar, in hopes that if she CAN'T lick she will break herself of any habit before it starts. We were also offered a onesie like the one Dennis
@DJC3 wore but after discussion and demonstration I opted for the E-collar. I doubt she will wear it much, as I have to remove it for eating and drinking and visiting the litterbox, which would mean a lot of taking off and putting on and she was seriously upset by just the fitting.
Good news is, the vet is not worried, the site is not infected, the KittenCat is not obsessively licking it, and I am available to keep an eye on it. As soon as we got home I let her out of her carrier and then took off again, to the grocery store, where I got us some nice cod, which we both love. Other good news is that some of the staff at the vet's clinic know one of the towns I am considering and have been able to tell me quite a bit about the town in general and the neighborhood in particular.
So now I think that, like
@PenguinMum and the furry girls, and
@HarryBeau and Plumpy, the KittenCat and I are going to stretch out on the sofa under a blanket and take a nap.
