Hi!~~
I just adopted a kitten with CH myself..he's about 4 months old now..there's a really fantastic group out there..Welcome to the CH Kitty Club
Everyone in the group owns a kitty with this condition, and there's so much useful information and support...I have found it so helpful that I visit the site at least once a day...I do know that several members do go the holistic route, so would definitely be beneficial for you to take a look!
From what I understand, very very often cats with this condition may also present with some visual impairment..but I would be very encouraged by reading some of the posts/stories/tips on the site...seems most seem to compensate for their condition!
Good luck!
