How many animals are in shelters?

Every year, 6.5 million dogs, cats, and other former pets are abandoned or lost and enter shelters. But of all these animals, only 3.2 million are adopted and many see shelters again after less than a year of finding a new home. Deciding to adopt a pet is an enormous responsibility. As such, many people choose to foster these pets as the shelters search for a permanent home. If you yourself choose to adopt permanently, be sure you are financially stable enough to support a living creature, have enough space for the pet to be comfortable, and that all other living creatures in the house (other pets, children, adults) are willing for such a big change. 

With publicly available data from the American Society for the Prevention of Cruelty to Animals, the Humane Society, People for the Ethical Treatment of Animals, we can better understand the unfortunate circumstances so many pets find themselves in, to better improve their short lives.

Pet insurance: Should you invest in it?

Pet coverage allows you to mitigate the risk of being on the line for the full cost of veterinary bills, which can be surprisingly expensive. Without such a policy, many pet owners find themselves in a tough situation. Just like standard carrenters or home insurance, pet insurance requires monthly premiums. For those premiums, your pet will receive coverage in the amount that you select. This can cover the full cost of your pet’s bills or only a portion depending on your policy. 

Below are the most common policy types and some of the situations they cover.

  • Comprehensive: While the name may vary, this type of comprehensive policy is robust and covers your pet with very few exclusions. Such policies are likely to cover hereditary conditions, vaccinations and illnesses such as cancer.
  • Emergency only: In this policy type, your pet will only be covered if injured in an accident. Illness and routine check-ups aren’t covered. This type of policy is most often used to keep high, unexpected costs down after an accident or injury.
  • Accident and illness: This policy type will cover emergencies and costs related to illness.
  • Wellness plan: This covers check-ups, routine visits and vaccinations, but may not cover illness or emergency care.

How much does pet insurance cost?

Pricing for pet insurance policies is based on a number of factors, primarily those specific to your pet. In general, the following factors are most likely to affect your pet insurance premiums:

  • ZIP code: More densely populated areas tend to have higher rates, as do areas where care is more expensive, i.e., California.
  • Species: The species of pet you own can play a big part in what you pay. Dogs, for instance, are often more expensive to insure than cats or many other animals.
  • Breed: Different pet breeds can also affect your premiums, as some may be more prone to certain types of illness or other medical conditions.
  • Age: Older animals cost more to insure.

Average yearly costs of pet ownership

The yearly costs pet owners face are most often dependent on the type of animal owned. Below you'll find a breakdown of the average yearly costs of owning a dog or a cat based on a study conducted by the ASPCA. These costs include a basic form of pet insurance, but the coverage levels are not clear.

According to the ASPCA, the average yearly costs for owning a cat are about $809 while the average annual costs of owning a dog are the following:

  • Small breed: $737
  • Medium breed: $894
  • Large breed: $1,040
