I believe the debate on rabbits living longer indoors than outdoors comes from the sad reality of the 'typical' rabbit in a small hutch at the bottom of the garden, more or less forgotten about- Becca I know your rabbits aren't like that! It's true I guess that with indoor bunnies just by the fact that they are indoors and you can see them all the time, you therefore notice any health problems sooner, because you are more aware of their behaviour on a day-to-day basis. Saying that, bunnies can live long and happy lives outside provided that they have adequate housing, and proper love and care...
Also, over here in the UK, our winters are quite mild in comparison (although boy do they feel cold to us lol!!) so it's not bad at all for bunnies to be out in this weather, as long as they have plenty of hay to snuggle in, and a hutch that protects them from the elements etc....
Becca, how is Dippy doing? Has he eaten anything at all today? Sorry if you said that further up..... I agree that it's definitely worth asking if your vet will make a payment plan- not all do but our vets are very open to that.... And as Flashy said, if there is a problem, it will be much cheaper in the long run to get it sorted now rather than waiting until it gets a lot worse
Edit to say, that by 'typical' I do not mean anybody or their bunnies on here!! I'm referring to the sadly all too true situation for a lot of buns who are misunderstood, not cared for properly, etc etc. I always think of a friend of mine when I was a child who had a bunny, but the more she forgot about him the further down the garden he was moved, and the less he came out to play. He died because he was neglected.
But that doesnt mean to say that all outside bunnies live like that
Hope I clarified that!
