Very wet girls part

[Bati]

Sometimes my girls (or many of them) are really wet on their private parts, it looks like they've been in a shower, but only on that part. Should I worry or are they just doing it for fun? Have had them to the vet but he says it's them playing

Are they older girls?

 

[Bati]

It's both old and young (down to 4 months), it's happening at random but when it happens it's almost all of them at the same time, they are 20 together. No signs of illnesses otherwise, just find it strange and a bit disgusting

 

[jorats]

How big is their cage? Do they have water bottles or water bowls?

Are they all on the pee schedule at the same time? I'm sure that sounds like a dumb question, but when I go in and wake my larger herd up to come out for playtime everyone goes and pees before they come out. So sometimes the ladies have a wet bum if I catch them in midstream.

Maybe I should take a pic, it's not just a 'wee pee', its a rather large area, walnut sized, and it's soaking wet. They have an ok big cage, they have bottles (and I haven't noticed any troubles with the bottle, the vet suggested some sexual activity, I do have 3 neutered boys in there (and they are not wet), but I haven't noticed the boys being involved

 

[jorats]

I highly doubt sexual activity but not unheard of.

So there's no spot in the cage that is very wet, that the girls could be making a puddle in a corner and getting a huge area wet?

 

[Bati]

No puddles, I use a thick layer of bedding and there is no chance of a lake anywhere, I've never seen the neutered boys showing any interest in the girls which is why I don't get it (and the amount is too much, and it's more water than anything else)
If you have any ideas what to look for / what to tell vet to check let me know
