Hi - I'm new to posting here! I have been reading and getting information from here for about a year now though. We adopted two boars (Charlie and Pickles) from a local rescue in October of last year. They were for my daughter's 11th birthday, but they are part of the family now. It has been an adventure. It has been very fun and we have learned a lot in a short amount of time. Charlie had sludge issues in February and we worked with a vet to clear it out. Then in July he was diagnosed with a huge bladder stone. He had surgery to remove it and is doing much better now. It was stressful because I felt like we were doing everything right - large cage, purified water, KMS hay and pellets, organic low calcium veggies, etc. After his surgery we switched to reverse osmosis water in a bowl and a bottle, limited Oxbow pellets (they have now removed the calcium carbonate), and bigger cage. We are hoping they stay happy and healthy. Thank you for all of the information we found on this forum. It has been very helpful!
