I hope he is ok! good Luck the only thing I might add is to keep an eye on him to make sure he doesn't cut or bruise himself either. The blood thinners in a small does case cause well thin blood and that a small cut can cause a quite server blood loss issue. The scary part it it can be hard to stop. I hope that he is doing ok and with luck he never got into the rat poison but ate something that didn't agree with him.
Good Luck!
