Zuzu is nearly blind; she had one eye removed as a kitten and can see only light and shadows out of her remaining eye. Since the eye damage happened when she was young, she never had vision. She wasn’t a fearful kitten; in fact, she was confident, bold, and sassy. I met her, loved her immediately, and that was that; she came to live with us.
I monitored the APA! website and found Jax, a 5-month-old ringworm kitten. I explained the situation to his foster, and she was confident that Jax was easy-going enough for Lyle and bold enough for Zuzu.
Everything isn’t perfect. She (and Jax) bother Lyle more than I like, but we manage that. Fido doesn’t trust her and never will, and frankly wonders why his house is overrun with cats. Zuzu will always be a sassy, high-maintenance cat, but that’s her personality; the agitation was her behavior.
