I think you have to look at both sides. Whilst yes, it can really come across as almost aggressive that we say "go to a vet NOW" etc etc, theres a reason we are all saying that.
It's called experience. We KNOW what can happen in certain situations. We've seen what happens if you leave a bun suffering from a GI slowdown/Stasis without veterinary attention.
Unfortunately, and i see this a lot...and its not just RU.
Situation (and yes, im using RU as an example, as its a discussion on here):
Joe Bloggs: "My rabbit isn't eating, she hasn't done for 2 days. She just sits in the corner of her hutch in the garden and doesn't move. What should i do?"
RU Member: "you need to get her to a veterinary surgery immediately. This could be caused by many things, such as dental issues (teeth hurt too much to eat), pain from soemwhere else, or some unknown, unseen issue, underlying, causing what is known as GI Stasis/Slowdown"
Joe Bloggs: "i can't afford to take her to a vet, and even if i could, i can't drive, and its 9pm and i live on my own in the middle of the countryside".
The issue is then forced by the unwillingness to provide one of the 'Five Freedoms' by the owner.
People come looking for one answer sometimes (note, i said SOMETIMES). They don't want advice, or someone telling them they need to see a vet. They want someone to tell them that it'll all be alright. That bunny will be fine.
This then becomes an argument between the OP and the people who know how this situation could end. Everyone gets on the defensive.
There's only one loser in this whole situation....
The Rabbit. Who is sat in her hutch. In Pain. Suffering.
I don't think i need to say much more.
You all know how i feel now.
Say what you will, its the truth.
