Do You Want a Pet That Lives a Long Time?

This is a question you should consider seriously before you adopt any animal. Getting a pet is not a light decision to make, so you'll need to be very realistic about how much time you can commit.

Choosing a Pet for Life

There are several factors to consider when choosing a type of pet.

  • Kids. If you have children, lifespan is an important consideration. It might be difficult for them to get attached to a pet only to lose it after a short time. On the other hand, maybe you want to choose a pet that only lasts until the kids go off to college!
  • Attention span. If you are the faithful, tenacious, dogged type, making a 30 year commitment won't be hard. But if you know that you tend to get distracted or lose interest quickly, you should avoid adopting a long-lived pet.
  • Lifestyle. Pets need consistency. If you travel often or can't be pinned down to a steady schedule, then many of these pets are not for you.
  • Housing considerations. Most animals' lives depend on specific environmental requirements (a yard, a pen, an open window...). You might not be able to ensure consistency if you rent or move often.
  • Financial considerations. When you take a pet on, you commit to taking care of them financially for life. The longer a pet lives, the larger financial burden it will be.
  • The last years can be the hardest. Old age brings complications and visits to the vet, so you should expect your pet's last years to be the most challenging.
