Thanks for all of your support everyone. You've brought tears to my eyes. I just received another e-mail from a woman in Cirrus's former rescue group and this is what it said:

Hi Tracey,

I have a fosterer who may be interested in taking him in –
I can let you know ASAP! She has one of Flint’s younger
siblings (we still have not caught that mamma cat)!


The potential fosterer is a nice woman who works with one
of our members, her name is Julie. She is currently
fostering a 6 month old who is from the same mother cat as
Cirrus. I have a feeling they would get along fine - this
kitten is shy and loves other cats. Would you be OK with
Julie visiting Cirrus to see if she wants to foster him? I
think she will when she meets him - she has a lot of
experience with formerly-feral cats and socializing them,
so him being shy would not bother her at all. She has been
a long-term foster home for several of our more
challenging kitties, and has really helped them become
more confident and adoptable.

This sounds like just the right person to foster Cirrus. I sure hope she'll be able to foster him. I'll keep you upated as soon as I know anything.
