We did not know that about white cats. My pet human will β into it.
Yes Lil' Guy has began to mellow. But We have to stay right on him. He cannot deny his instincts to hunt and attack anything that moves. Except for me. He seems to have respect for me. And my human gives him a stern loud voice when he even gets near me. "Leave her alone" he thunders at him... He is very protective of me... M.O.L (meow out loud)
I'm glad to hear there's progress. Take a look here https://icatcare.org/advice/inherited-deafness-in-white-cats/
