Traps not going off

I have a question:
I have mice in the house, everytime I set the traps the mouse sets the trap off takes the food. Please let me know what I can do I have to get rid of them.
I do have a cat in the house but he is retired. I do not want to put poison down in case my cat eats it.
Answer:
What is probably happening is that the traps are being set too fast, they go off before the mice find them and the mice eat the peanut butter without fear of being snapped. Some traps have a fast and slow setting, look closely for "s" or slow setting. The trick is not to set the trap too fast. Let the mice have a chance of sniffing out the peanut butter. Never use poisons inside the risk is too great especially with your retired cat. Mice can drop little bits of poison onto your cat's food and suddenly you have a very sick cat.
