Agree with Eddie above. The current mud slinging, lies, drama politics in the US is enough to not want another layer of this type of political chaos in our country.
Usually when something gets subsidised everything goes up in price. So I say no to subsidising people for vet care. If you can’t afford costs of say a dog or cat then look at getting your kids a bird instead.
Subsidising cost of desexing for cats and dogs (males and females) would be the only surgery that i believe would be advantageous.
