Next morning

Sunlight glinting on the sink reveals
there is no minty goodness, -- You could maybe put minty goodness in quotes as if it were an advertising slogan.
only remnants of another evening to regret, -- I don't think you necessarily need regret here. The extra syllables help with a "flow," but I think the word weakens the content (you know, on a lexical level or something).
sad little crumbs of smudged lipstick, worn
elastic, despair. -- I'm not sure I like the list descriptors here.

Bunny came from a crowded burrow, -- I think bunny is a pretty good name, if this is fictional.

Bunny brushes away the taste 
of the dog that whimpers
until it stops.

I left some comments. I think there is an interesting aspect of sound where lines end in the middle of lists that could be used to present a type of culture.
