I am so so sorry to here about tinkerbell, its heartbreaking to loose a pet and like someone else said, do you ever really get over it? We lost a cat to a car accident in 1997 and i still cry about it

As for another cat, thats up to you....we never could as we dont want to feel like we're just replacing a lost cat, but everyones different. If you wanna get another cat then do it!
