The Case for Rats as Pets

This article relates to Blood Test

Rats are polarizing animals. In some people, they evoke feelings of fear and disgust, thanks to their historical association with squalid settings and the spread of disease. But others find them adorable and friendly—the sort of creature that makes a great companion.

In the book Blood Test by Charles Baxter, the main character is sold a pet rat at the urging of a healthcare startup that predicts caring for it will benefit him. While his girlfriend is grossed out, his teenage children take to the new furry friend immediately, carrying it around on their heads and shoulders and feeding it off the dinner table.

Veterinarians say rats are much more intelligent and social than people give them credit for. They can be taught to perform tricks like coming when called and are unlikely to bite unless provoked. Rats form close bonds with their owners and actually laugh when tickled, in the form of a high-pitched squeak. When they're happy, their ears turn pink. Unlike their popular image, domesticated rats are very clean, and aren't known for causing many allergic reactions.

The downside is their short lifespan. The average pet rat lives just 2-3 years. And while it's advised to have more than one rat to keep each other company, if a male and female rat are kept together, be prepared for a baby boom. Rats can give birth up to seven times a year, with an average of seven babies per litter.

The bond some form with their pet rats makes caring for them a joy. In an interview with The Washington Post, rat owner Abby Chronister says her tiny pets got her through a rough period of anxiety and depression: "Those little critters are what made me get out of bed, knowing I had those little lives to care for. They bond with you like a dog does. You might not have the energy to walk a dog, but you can manage to fill a water bottle."
