Are there any decent pet burial service places in Chennai?

I recently lost a cat and have 3 other cats that are near and dear to me. Before the loss, I never really thought about this but now I have to plan for this eventuality. It pains to me even realize that I have to plan for this so that whenever that dreaded day comes, at least I know what to do. If any of you know of any services or places please let me know. Also is there a service where they bury your pet and then plant a tree on it or something like that do let me know.
