Grade A â Eggs appear to be the same as Grade AA, but the difference is a slightly lower interior quality. These type of eggs are commonly sold in local supermarkets. Grade B â Eggs are noticeably different.
Rodenticides, colloquially rat poison, are typically non-specific pest control chemicals made and sold for the purpose of killing rodents. Some rodenticides are lethal after one exposure while others require more than one.
I also used poison and now have cats. I am a firm believer in poison in the house, to get rid of the mice that are actually in the house. A word of caution though, my first cat got into the poison and died. To get rid of mice you must prevent them from finding food, shelter, and safety in your house. Commercial mouse poison works well.
