Not being argumentative, but what brand? And how would it work? How would it kill a mouse and not the animal that eats the mouse?
Mouse “poison” that are anticoagulant such as chlorophacinone, brodifacoum, bromadiolone, difenacoum, difethialone, diphacinone and warfarin is highly unlikely to kill a pet or larger mammal if it eats a dead mouse killed by it.
The dose to kill a mouse is insignificant to a pet. These are blood thinners and some such as warfarin are even proscribed to people.
Vitamin K1 can be given as an antidote and is effective.
The danger with these poisons is if the pet or other larger mammals get to the bait is set out and ingested directly in larger amounts which is why good bait stations are important even with these products.
Other poisons shut down kidneys and can be easily passed up the food chain and antidotes are not very effective.
Best is just not to put any thing out and use traps.
