If you have a pet you should always get pet insurance as it will cover health related costs and even emergency surgery should your pet need surgery or other medical procedures done.
Taking your pet to the vet can be costly and having Pet insurance is a must so you vet bills will be covered.
There will likely be a deductible you'll have to pay to have the pet insurance cover the medical bills for your pet but it's still cheaper than coming up with the full amount of money the vet will cost you.
