Mooie returned on Palm Sunday from being missing for five weeks. We really had given up hope and assumed that maybe someone was feeding him/taking him into their home, or he had found his previous owner.
Moo Cat is a stray, neutered male, and we began caring for him when he appeared at our doorstep after (as yourself) putting food out in hopes that Mysty would return. This was the fall of 2003. Instead of Mysty returning, we brought Punky, a malnourished and weak feral tortie kitten into our home,
and Mooie, who took up residence on our back porch.
Mooie left when we had a warm spell, which was followed by a horrible winter storm, more cold, freezing days, and more snow. The day he returned, we saw a cute, petite white and soft grey patched older kitten bounding about the yard and the back porch. It was getting close to sunset that day, and who was sitting patiently at the back door, but Mooie, as if nothing had happened! We were shocked and really surprised. Mooie looked the same and it was as if he had never gone missing for so long. I just thought I have bad luck with male cats (Mysty), and we lost Mooie, too. That day turned out to be such a pleasant surprise!
As yourself, I, too, canvassed the neighborhood for Mysty. I went walking door to door in tears, dropping off lost cat fliers to the neighbors on an extremely busy road near us. I was in tears because the cars traveled so fast on this death trap road that no animal had a chance if he tried to cross it.
Some stories have happy endings, so I sincerely hope that your kitten returns home. Good luck to you!
