GP not drinking

[123rd]

We have 2 male gp, just turned a yr old.
They have both stopped drinking from the water bottle.
I've tried cleaning it out, making sure it isn't blocked. Still no luck.
So bought a brand new one last weekend and they haven't touched it. And it's defo within their reach.
They do spend most of the day outside now it's sunnier but inside to sleep.
They seem as active and squeaky as normal.

Any ideas??

Are they peeing as much as usual?
My piggies usually shun their water bottles in favour of vegetables/salad.
Even in the height of summer.

If this is a new thing, it's likely to be the bottle or the water . If you tap the end does the water come out where the ball bearing is ? If it's not easy to use they won't bother (or they'll make a load of noise doing so)

Our GP7 likes to rattle the water bottle against he bars, I was worried that she was drinking more than usual , but I watched her - it's rattle rattle then a small drop drunk. So she's playing with it more than anything.

You can give their veg a quick rinse to leave some water clinging to it .

Keep a check on their pee output .
Might be an idea with boars to give them two bottles spaced apart in case they argue and push the other one away from the water .

These two are a lot more fussy than our previous boys. And yes, it is a fairly recent thing.
The brand new bottle defo is fine

I haven't actually checked their pee. Already thrown out the dirty stuff form their cage so will redress and check tomorrow morning

Thanks
