What can/must the owner do in the case of these illnesses?

Many rabbits and guinea pigs suffer from bladder stones or bladder grit.

The most common types are calcium stones or calcium grit.

The first symptoms are often changes in urination. The animals' abdomen and genital area are moist or even wet. The urine has a strong odor and may even be bloody. The animals strain to urinate and often vocalize in pain while doing so.

The animals are very restless, often behave aggressively, and eat poorly.

In the course of an undetected illness, the general state of health can deteriorate dramatically and rapidly.

At the first signs of illness, the animal should be taken to a veterinarian immediately. X-rays and ultrasound can diagnose stone/crystal formation and initiate necessary treatment (medication/surgery).

What are the most common causes of bladder stones?

• Malfeeding with calcium oversupply
• Feeding exclusively with dry food
• The animals are drinking too little.
• too little exercise / overweight

If stone/gravel formation is diagnosed, immediate changes to feeding and husbandry are necessary!!

The cage should be appropriate for the size and number of animals. Obesity must be avoided at all costs; regular weighing is advisable. When removing the animal from the cage, for example for cleaning, the entire animal should be checked for any changes.

Check the food and water supply:

• Fresh water must always be available. A water bottle AND a water bowl are needed; preferably still mineral water (low in calcium), as the water in Karlsruhe has a high calcium content.
• The animals should be fed primarily fresh food, as this encourages them to consume additional water. This increased water intake dilutes the urine and may help flush out any grit.
• fresh grass, meadow herbs, leafy vegetables, fruit, birch leaves, dried nettles, fruit and vegetable juices (without sugar)
• The animals should receive so much succulent feed that they only consume a small amount of hay.
• Avoid dandelion, parsley, kohlrabi leaves, clover, and dried herbs.
• Do not feed hay rich in herbs
• Absolutely avoid grains, hard bread, green rolls, ready-made feed and limestone.

Additional medications from the field of alternative medicine can be used to dissolve stones; consult your veterinarian.

Once the illness has clearly healed, an expansion of the feed can be discussed with the treating veterinarian.

Introduction

Bladder stones and bladder sludge in rabbits and guinea pigs can be a painful and distressing experience for both the small pets and their concerned owners. This comprehensive guide sheds light on this important topic and helps you recognize the symptoms, understand the causes, apply appropriate treatment methods, and implement effective prevention strategies.

Bladder stones and bladder gravel: What are they?

Before we delve into the details, let's briefly look at what these two terms mean.

• Bladder stones (urolithiasis): These are hard, stone-like deposits that can form in the bladder of rabbits and guinea pigs. They consist of minerals and other substances that are normally dissolved in urine.
• Bladder sludge (struvite): These are fine-grained, sand-like deposits in the bladder. They form when certain minerals, especially magnesium, ammonium, and phosphate, combine in the urine.

Causes of bladder stones and bladder sludge in rabbits and guinea pigs

There are several factors that can contribute to the formation of bladder stones and bladder sludge in rabbits and guinea pigs. Here are some of the most common:

1. Nutrition: An unbalanced diet rich in calcium and/or phosphorus can increase the risk of bladder stones and bladder grit. Insufficient fluid intake can also contribute to the formation of these deposits.
2. Genetic predisposition: Some animals are genetically more prone to the formation of bladder stones and bladder grit.
3. Infections: Bacterial infections in the urinary tract can lead to inflammation, which promotes the formation of bladder stones and bladder grit.
4. Lack of exercise: Lack of exercise can cause urine to accumulate in the bladder and increase the concentration of minerals, which promotes the formation of deposits.

Symptoms and diagnosis of bladder stones and bladder sludge in rabbits and guinea pigs

If your rabbit or guinea pig is affected by bladder stones or bladder sludge, some signs may include:

1. Frequent urination: The animals may try to urinate more frequently than usual to relieve the pain and discomfort they are experiencing.
2. Blood in urine: In some cases, blood may appear in the urine, indicating irritation or injury to the urinary tract.
3. Signs of pain: The affected animals may show signs of pain, such as restlessness, loss of appetite, teeth grinding, or an unusual posture.
4. Difficulties urinating: It can happen that the animals have difficulty urinating or even stop urinating altogether if the deposits block the flow of urine.

To diagnose bladder stones or bladder sludge in your rabbit or guinea pig, a veterinarian should be consulted. They can perform a physical examination and, if necessary, use further diagnostic procedures such as X-rays or ultrasound scans to determine the exact cause of the symptoms.

Treatment of bladder stones and bladder sludge in rabbits and guinea pigs

The treatment of bladder stones and bladder sludge depends on the size and type of deposits, as well as the animal's overall health. Some possible treatment options include:

1. Drug treatment: For smaller bladder stones or bladder grit, medication can be used to dissolve the deposits and reduce inflammation in the urinary tract.
2. Dietary management: Adjusting one's diet to reduce calcium and phosphorus intake and increase fluid intake can help dissolve existing deposits and prevent future deposits.
3. Surgical removal: In severe cases, Surgical removal may be necessary, especially in the case of larger bladder stones that block the flow of urine.
4. Antibiotics: If a bacterial infection is present in the urinary tract, the veterinarian may prescribe antibiotics to treat the infection.

Prevention of bladder stones and bladder sludge in rabbits and guinea pigs

To minimize the risk of bladder stones and bladder sludge in your rabbit or guinea pig, you should take the following measures:

1. Balanced diet: Make sure your pet receives a balanced diet that is high in fiber and low in calcium and phosphorus.
2. Adequate fluid intake: Ensure your pet has access to fresh, clean water at all times to guarantee adequate fluid intake and dilute urine concentration.
3. Regular exercise: Ensure your rabbit or guinea pig gets enough exercise to promote bladder emptying and maintain urine flow.
4. Regular visits to the vet: Schedule regular veterinary visits to monitor your pet's overall health and detect any potential signs of bladder stones or bladder grit early on.
