What did you do with the dead pets?

Our cat disappeared. So we don't know where she went. One if my grandmas cats did the same. They had many cats over the years and when they past away grandpa would bury them behind the bushes in the back yard. If our kitty had died at home we would have done the same for her. I have parakeets now and I think when they go I will put them in s ziplock and out that in a box and throw it away. That way there won't be a smell in the dumpster.
