I have a kitten that's been possibly diagnosed with osteogenesis imperfecta. Any ideas that you all have for any supplements?

This isn’t a very common condition in kitties. Multi Essentials for multi vitamin support might be beneficial in this case. Turmeric might also be beneficial for anti-inflammatory and anti-oxidant support. This condition likely causes some degree of pain or discomfort, so the Turmeric can help to ease this discomfort and help to protect against oxidative damage.
