Cat with idiopathic hypercalcemia

Hi! I’m desperately searching for the right remedy for my cat for idiopathic hypercalcemia. His test results were very concerning. His blood calcium was 14 today at the vet.
He was there for a dental and they did the bloodwork and weren’t able to do the dental because of that test result. The vet requested that we do an ultrasound and xray to rule out any mass and both were clear. They are sending out more blood called “Malignancy Profile (PTH, PTHrP, ICa) and I’ll have those results by Monday but this is so concerning to me. Whatever is happening I want to treat with homeopathy. My cat is a 7 year old male, neutered, domestic short hair. He weighs 16.25 pounds. He’s had no symptoms except for he’s been extra aggressive with the other cats, which led me to believe it was his teeth as I saw that he had the start of a resorptive lesion on a molar. I figured the extra aggression was from pain due to the tooth. But then this hit me right out of left field. My kitty is a rescue, who just showed up at our doorstep in 2019 with severe frostbite on his toes. We got him vetted and he had surgery to remove the one toe that wasn’t savable due to the frostbite. So he’s been through trauma though we don’t know what exactly. He’s always been aggressive and I’ve tried countless remedies for that. But the aggression got worse over this last month, hence the dental today which ended up not happening. I’m searching for help for him. Thank you in advance.
