We have two cats in our house that were both feral as kittens but were brought into the home. We made sure they underwent the neutering procedure, and since then, Prufrock, the female, is skittish and scared of everyone and everything but me. Roman, the male, is docile and loving to everything but moths and flying insects.
Here's to hoping that your fur-buddy makes it through and learns to love his human.
Hahahaha. Thank you so much for the encouragement. Great names your kitties have...and they're lucky to have such nice family as you all.
