We also bought a tiny orange PFD for our black cruising kitty, Onyx. Unfortunately, every time we tried to put it on, she lay down and refused to get up. The brand name is “Fido” and Alex's theory is that she isn’t very happy with that. We were quite concerned about her when she was a kitten but she's got such great sense and sealegs now, we are quite confident that she won't go anywhere near a dangerous situation on her own. (she has been cruising with us for over 13 years now - including three Atlantic crossings) Luckily, she prefers to sleep below or snugly under the dodger while we’re underway, but we do have it should we need it. here
