i'm so sorry for your loss on your kitty.this is very very sad.
i know how hard this must be on you.
i wish i didn't see the pictures
it's the way it had to be.it's very hard to find a cat a great home that pees
all over the place for just behavioral problems.
sometimes a home with no other pets or noises may be the only solution.
but,who wants to go door to door all over the USA and see if they have other pets or if they are a noisy home....lol
(i'm trying to help you crack a smile).
but,even that is only a pot luck thing...they still may pee everywhere.
plus,someone else may hurt the cat for peeing.
the guilt of not knowing is just as bad.
i hope you can come to terms knowing that you did what you had to do.
it's hard but it had to be done.
try not to be so hard on yourself (i know,shush....lol,easier said,right?)
i'm sure most people will agree with what you did.
be well.
we love you and i'm going to say a prayer for her and one also
for you
