Flystrike In Rabbits
Flystrike (also known as myasis) is a serious condition in rabbits caused by flies laying eggs on their body. These eggs hatch out into maggots that feed on your rabbit. Sadly, flystrike is often fatal within 24 hours.
Although any healthy rabbit can develop flystrike, there are factors that increase the risk:
Warm weather - the fly population increases over summer, although it’s important to remember that flystrike can occur at any time of the year
Poor diet - this increases the production of soft faeces called caecotrophs, which can easily become stuck to the rabbit’s fur
Elderly, obese or arthritic rabbits: - can struggle to clean themselves properly, particularly their rear, which can result in a build-up of faeces and urine
Long-haired breeds: - breeds such as angora rabbits are much more prone to picking up dirt and faeces, and equally difficult to keep clean
Dental problems - rabbits with painful dental issues are often reluctant to clean themselves thoroughly
Open wounds - the scent of blood from an open wound can attract flies
Poor living conditions - dirty hutches can attract flies, which puts the rabbit living inside it at risk
Females with large dewlaps or skin folds around their abdomen - these can make it difficult for the rabbit to clean and groom themselves
Preventing flystrike
Prevention is essential to keep your rabbits safe from flystrike. Check them over every day, with special attention around their bottom and tail. This should be increased to at least twice a day in summer. Speak to your vet for advice about keeping your rabbit clean of urine and faeces.
Keeping their environment clean with fresh bedding will also help keep flies away. Bedding and litter should be refreshed every day, with a thorough clean out at least fortnightly. Don’t forget to use pet-friendly disinfectant every time you clean out to kill bacteria.
Make sure your rabbit’s diet is primarily hay-based, with a small portion of fresh vegetables and an even smaller amount of high-quality pellets (a ratio of 80-15-5). This will keep their weight in check and ensure they don’t produce an excessive amount of caecotrophs (although it is normal for your rabbit to produce some, as eating them is an essential part of their digestive system).
Keep an eye out for sores or open wounds and ensure they’re kept clean and dry. If your pet is elderly, arthritic or has large skin folds, take extra care to ensure their body is clean and dry to reduce the risk of infection. For long-haired breeds, carefully trim away excess fur around the tail and bottom in summer months to prevent a build-up of urine and faeces.
There are products available to protect rabbits that are at a higher risk of flystrike. These include spot-on formulas and sprays that prevent fly eggs from developing. Speak to your vet for advice that’s tailored to your pet.
