OTOH (I was just reading the other day), cats can't even see red (looks grey to them) ... only green and blue. Looks as though higher-freq visible light worked just fine for Feliformia. The organs/antennae needed to send and/or receive RF would be highly ungainly for speedy smaller predatory mammals.

Who knows - maybe some of the dinosaurs -did- use RF?! High EMF from solar CME's might have burned out their receptors.
