I had never heard of it so I looked it up on the internet, I will be of absolutely no help. It looks kind of like the Banfield plan only you aren't tied to just a Banfield clinic for vet care. I know with Banfield it is kind of like making monthly payments on routine preventative care. I read what were supposed to be reviews from other sites and people consistently say that they are reimbursed quickly. I probably wouldn't use this type of plan and would go with a regular insurance plan that reimburses some of the expenses for illnesses and/or injuries. I can plan for the routine wellness visits, I can't plan for those large unexpected bills.
I was thinking of pairing it with another, more typical insurance that covers accidents and medication. I am pretty sure she has some un-diagnosed ailments that could end up being pricey, with multiple visits and blood work.
