Coco the guinea pig that is 
Poor girly is squeaking when she has a wee
She is being more of a Diva than usual, sitting facing the wall of the hutch. Millie Pig is bullying her too. I think she has lost weight but her eyes are bright and her fur is in good condition.
Also she has always drunk a lot and eaten a lot of Burgess Pellets. Today she was very greedy for cucumber and asked for more.
Last night I had her sat on me for a parsley treat (the other girls hadn't let her have any in the hutch) and she did a squeak, drew up her body and squirted out a big white wee. She always looks more relaxed after she's had a good pee on me 
My guess is either too much calcium in her diet but the only thing that is high that they have is spinach and they don't have it every week and the other two are fine.
Or I could change to Wagg Crunch for guinea pigs, its lower in calcium but its a muesli 
Or treat her for cystitis and give her cranberry juice. Anyone had any experience of this? Do I give it neat or diluted, if so, how weak?
Last resort, trip to vet for Baytril if its an UTI.
What opinions do my fellow SFA slaves owners have?
TIA
