I don't think there is any Chet's to get free bones but for coins at the start I had like 400$ and now I have 29504$ and all I did was play the game I got to cats and would breed them and then I would sell the baby's and after you get a some more money in then start buying the more money ones I do not have a lot of bones I only have 2 right now
If you have no bones then
Go to the paper with a check on it click it and it will tell stuff to do if you complete one of them sometimes they give you bones or money or little stuff like that
