On 22 Oct 2008, Greyyie, my Sheltie had died of a failure of operation for bladder stone.
They found some crystals and a stone lodged deeply inside the bladder. During the night, he was squeaking, unable to pass out urine. His pasage of urine was obstructed.
High level of certain minerals in food can increase the chance of crystal formation in urine. The minerals magnesium and phosphorous are components of the most common crystal type - struvite.
Therefore it is helpful to keep the levels of these minerals as low as possible.
The pH of the urine influence the chance of formation of crystals and calcium oxalate. Struvite tend to from in more alkaline urine, calcium oxalate in association with more acidic urine.
Therefore feeding a food that results proper urinary pH is essential to reduce crystal formation.

What must we feed our guinea?
Recommendation1. Do not overdose on Vitamin C, ascorbic acid!Because Vit C is acidic, overdosing will result in acidic urine.
Don't think that the more Vit C the better. Sometimes, these little animals already have enough Vit C through their fruits, vege and diet.
Sometimes, we can just skip supplementing once a while and
it's important to know what's the right dosage to give. Excess Vit C will only be passed out. Over supplementing is also detrimental.
If the urine is too acidic, it will tend to form calcium oxalate as mentioned above. If too alkaline, crystals like struvite will form.
All these are what we called "stones".
2. Stop 24 hours supply of commercial foodWe don't know exactly what is the real content of the commercial food and they probably have very bad MAP-Magnesium Ammonium Phosphorous balance.
Last time, i loved my guinea so much and always bought expensive pellets for them, and the pellet food bowl was all the time filled up, never empty. This allowed them to eat the whole day, without knowing all the bad stuff and minerals had been accumulating in their system.
And one day, my Greyyie urine system failed.
Now, i have realised that the commercial food is one of the main cause.
It doesn't mean that we should stop giving them, but it means giving them at appropriate amount, maybe feed them pellet food once accasionally.
3. Provide continous supply of grass, hayBeside vege and fruits, I recommend my guinea take these as
staple diet because they are natural organic food.
And i recommend timothy hay, it is very good!!
Beside timothy, Every week, i will go to the hills area and cut natural long cow grass for them, and they love the cow grass, these cow grass are very rare in the city area where we live.
Grass , hay is my guinea staple diet now.
How old is your Greyyie? Is it a male? I think male GP have more tendency to develop than female.
