JT Eaton Answer Gopher Bait is pet safe if used as directed on the product label. The risk of secondary poisoning is very minimal. Generally, a gopher would only need to consume a small amount of bait in order to receive a lethal dose, so even if a cat were to eat a dead gopher it is unlikely that the cat would be able to consume enough bait to have a harmful effect. In most cases, well-fed domesticated animals will not actually eat a dead animal such as a gopher that they come across. Instead they will play with it or chew it and then leave it behind.
According to JT Eaton Answer Gopher Bait's label, "Do not apply directly to water. Runoff also may be hazardous to aquatic organisms in water adjacent to treated areas. Do not contaminate water when disposing of equipment wash water or rinsate." The product will not leach into the soil or into the well water unless it falls directly into the well. We would recommend to take precautions such as not using the bait within 20 feet of the well, or avoiding use if an active tunnel heads directly towards the well.
