Apple
Species: Guinea pig
Status: Sanctuary resident
Condition: Confirmed osteodystrophy (satin syndrome)

Apple is HALT Rescue's first guinea pig to be officially confirmed as a satin carrier with osteodystrophy. He is only 8 months old — heartbreakingly young for a diagnosis like this. He has already had a seizure and is showing signs of pain in his hindquarters.
His Diagnosis
Apple's osteodystrophy was confirmed after a thorough veterinary workup. The satin coat gene, which gives some guinea pigs their distinctive shiny fur, is linked to a metabolic disorder that prevents proper calcium absorption. Over time, this leads to painful, weakened bones. In Apple's case, the disease is progressing early.
His Care
Despite his diagnosis, Apple is described as adorable and sweet. His care team is focused on keeping him comfortable and monitoring his progression. He receives supportive care and pain management as needed.
Why This Matters
Apple's case is a reminder of why HALT strongly discourages purchasing satin-coated guinea pigs from pet stores or breeders who do not screen for this gene. The satin gene is associated with a painful and ultimately terminal condition.
