I've read that straight urine will burn roots, so I'd dilute it if I was to do this, but I never use fertilizers because they're salts, and my theory is with all the road & side walk salts that have built up over the decades if I put any more salt into the soil, it'll end up like 'Idiocracy'. "It's got electrolytes" = it has salt. I've never had a problem with garden plants needing fertilizer, and I think it's a short term gain vs. a long term turn the world into a desert planet like Mars thing.
I think the vet followed his heart and saved a life. I think the diplomat plopping out money for a lawsuit lawyer, but not what the cost would be for surgery says much about that person's character.
