It's wicked the prices that have to be paid nowadays for veterinary treatment.
I had alot of animals up to 5 years ago, when I lost my last one and I was extremely fortunate for a number of years to have a brilliant vet, who did her utter best for my animals and kept my bills low, sometimes just covering her costs. Sadly for me, that changed when she emigrated and the vets bills became a huge headache.
It's no wonder there are so many unwanted animals, people can't afford to have pets.
It is more business focused these days and the compassion is £s & pennies, very sadly.
Sorry to hear of your girlfriends loss. Our pets can be like family and it's gut wrenching to see them go to Rainbow Bridge.
