*hugs* losing a furkid is one of the hardest things in the universe I think.
You made a very rough decision, and put Kaila's wellbeing in front of your own desires, which is the very best thing that a responsible person can do.
I've had to make that decision three times now, and it totally sucked all three times. My thoughts are with you, and George the cat is purring for you.
I know that Kaila is up at the Rainbow Bridge, happy and healthy and running around with my childhood dogs waiting for you for a happy reunion someday.
