I hope that you don't mind me asking but my guinea pig (an 18 month old boar) squeals in discomfort when it seems he is passing a poo. He arches his back and goes very still then is OK. This has been happening on & off for a while but then i cut out all high calcium foods I have researched & just feed him his Excel nuggets, sweet pepper, cucumber, carrot, apple, courgette, hawthorn occasionally and lots of herbs. He has Select Timothy Hay all day long too. I will get him to the vets to be checked over but can you suggest anything to give him? I have tried FibrePlex but he isn't interested in this at all. Our water is high in calcium, is bottled water OK? I was thinking of changing to bottled?
Hi!
Please see a vet as your piggy could have sludge or stones, a cystitis (bladder infection), or something stuck in his penis shaft (semen rod).
Boar Care: Bits, Bums & Baths
Please be aware that your diet has become very unbalanced as result of your efforts; it is far too high in sugars, which can lead to severe bloat and other digestive problems in the longer term (dysbiosis = overgrowth of bad bacteria in the gut that unbalances the normal fermentation process).
The majority of calcium comes via the water and the pellets. Unfortunately most people are not aware of the fact that filtered water and and just 1 tablespoon of pellets will actually go much further in reducing the calcium in your diet. Even the pellets lowest in calcium still contain more of it that the same quantity of the veg highest in calcium. You should also not cut out all calcium altogether because that can be as detrimental as too much.
Please keep your diet as green as possible and feed a very little high calcium herbs or veg together with plenty of low nutrition but higher fluid content veg to ensure that the bladder is well flushed. Herbs, greens and their stronger relative, kale, contain other important vitamins (including vitamin C), important minerals like magnesium which are not in pellets, and trace elements.
The best fresh food is fresh untreated and dog pee free grass and hay. Fresh green growing grass is high in vitamin C; it is the reason why guinea pigs never had to make their own in the first place. Even hay contains it - and hay should make around 80% of the daily food intake as the nutritious silica rich fibre is crucial in keeping the chewing back teeth ground down and the gut microbiome healthy.

Make sure that you introduce any fresh grass gradually in order to not cause diarrhea or bloat by feeding too much too quickly. Detailed tips in here, including how you count fresh grass into your overall diet at different times of the year:
