Boxers are not known to have a high prey drive. This makes them an ideal breed if you own other pets such as cats. It means that you can teach, train and socialize them to be able to interact with other animals more easily, and it also means you are less likely to encounter issues when leaving them to their own devices in your backyard. However, some boxers are hyper and will chase other animals. This is not to say they are trying to cause harm - but are looking to play, run around and have fun.
