Thanks for the high-quality feedback here. MB, I think you’re right about the scent business. In any case, bobcats rely more on eyes and ears than nose, it turns out, so if/when i rewrite the poem, i might excise that line altogether.

David, that’s interesting about the partial color-sightedness. Maybe they are like people with red-green colorblindness? The ethnobotanist Gary Nabhan has an intersting essay about that condition, which he has himself, and how it can be an asset in certain situations, making certain things in the landscape (not fruit) jump out for him.

(Update) – Yes, cats have red-green colorblindness, according to a web article that Rebecca Clayton dug up (see previous comment thread).
