I looked it up and the question is answered here:http://www.domyownpestcontrol.com/contrac-blox-rodenticide-questions-pq-80.htmlBasic summary, mice eat very little of the poison. Therefore a cat would have to eat 20+ of such mice to have an issue. And they go into further detail. **Q: Does this product lose potency over time? How long is the shelf life before you need to buy new poison?** A: We buy a bucket about every year works great! **Q: How long does it take to kill rats after eating it** A: Within a couple of days. **Q: can we purchase 'one' 4lb pail? instead of 4? one of these lasted me several years previously i don't want them to go bad.** A: No it is illegal.
