Pet insurance for an indoor cat

I have a relatively young tabby cat who’s about 4 years old. Fortunately, she’s very healthy and we haven’t had the need to visit the vet for her. But, as I’m seeing more posts about people putting down their cats and also having to pay for occasional health related issues, the more I find myself wondering “should I get her health insurance? Please share your experience if you currently have or have had pet insurance in the past, thank you.
