I checked out insurance previously, and did it again for my horse this summer.
One thing to be wary of is, that what you have going on right now would be a preexisting condition and will not be insurable. And that body system or body part (sorry not sure what the health issue is you are dealing with!) may never be insurable.
I’ve heard great things about VPI.
Key things imo to ask when buying pet insurance:
-what is covered-routine, exams, diagnositics, surgeries, major medical, specialists etc
-how much of that is covered? Is it a yearly total, a policy total or a percentage? Or a combination?
-How do you get the claim covered? Do you pay and get reimbursed? Do they provide a card to pay with?
-How many claims/percentage of claims to they turn down or approve?
-What types of things are never insured? -For example many horse insurance companies don’t insure colic or lameness.
-What would void your insurance?
-If you make a certain claim (say GI Stasis) -when are you eligible to claim for that again? (because often it’s then preexisting and you can’t claim for a year, or ever again)
Compare your annual costs to what you could potentially pay in vet bills (See the https://binkybunny.com/BUNNYINFO/tabid/53/CategoryID/4/PID/940/Default.aspx page for a good idea) and see if you wouldn’t be better putting that money aside.
