Tara Parker-Pope finds a study:
Most pet owners (62 percent) said they would likely pay for pet health care even if the cost reached $500, but that means more than a third of pet owners said that might be too much to spend on an animal.
What if the bill for veterinary care reached $1,000? Fewer than half of pet owners said they were very likely to spend that much at the vet. Only a third said it was very likely they would pay a $2,000 vet bill.
Once the cost of saving a sick pet reached $5,000, most pet owners said they would stop treatment. Only 22 percent said they were very likely to pick up $5,000 in veterinary costs to treat a sick dog or cat.
