You can't compare human care to vet care.
Yes they are our fur babies, but at the end of the day- they are a cat - an animal and considered a luxury. I am under the belief if someone can't afford a pet, they should not have one.. period.
I know that I am disabled, on a fixed income and it would be hard for me to come up with $180 on the spot (to pay out, no problem) but on the spot- not happening.
I could make payments and would probably take a few months to pay it out- but it would be paid eventually. Luckily, I have a vet that works with us- anything we need they do it, and they let us pay it
out.
Also, how do we/they know the care was the absolute basic needed for survival? Extra tests and stuff shouldn't happen. When I worked on the ambulance and in the ER as a paramedic, and we had a kiddo come in without a parent, then consent was only implied for "NECESSARY LIFE STABILIZING TREATMENT" . Example - shocking a heart rhythm back to normal, but not doing optional cardiac tests- only what was necessary for life stabilization. The same should somehow apply to stray pets. We have something called the EMTALA- You re probably familiar with it, Emergency Medical Treatment and Labor Act" - "It is the law, If you are having a life threatening emergency or are in labor, this hospital will treat you and provide necessary treatment for stabilization, regardless of your ability to pay" signs hang in hospitals everywhere.
Unfortunately, there are no vet similar things that I am aware of.
If it ever got to a point where there was no way on earth I could pay vet bills, the cats would go to a new home - and as hard as it would be, that would be the best thing for them.
