We used to get a lot of calls from people who could afford vets but resented paying for them
Exactly and for all we know, this could be the woman in the article. People like this are a fucking disgrace. The fact is, many people are fully prepared to 'wait and see' to save a few pounds, even if that means their animal is suffering. Many can't even be bothered to phone a vet. You can see this just by reading some of the threads in the Doghouse or on other pet/dog forums.
Telephone advice from a vet is free of charge. Anyone can ring a vet and say 'I think my cat might have a broken leg/it is limping' and th evet will advise whethr it needs to be seen or whether it can wait. If it does need to be seen as the animal is suffering, vets are legally bound to prevent that suffering, regardless of whether the client can pay.
