I am so sorry about your cat. You did the right thing.

I had a little dog I rescued from the streets that I placed in a loving home when I was homeless for a time. She was a little escape artist though. She ran away and was run over. So sometimes giving the pet a merciful end may be better. Even in a loving home, if they don't know the animal's peculiarities, something can go wrong.

I am so sorry for your loss. Take care.
