Dogs will eat almost anything—cats, not so much. Here’s why.

     Why are cats such picky eaters when dogs seem willing to wolf down just about anything they encounter? It’s a question many pet parents likely ask themselves while __________ their feline friend to swallow a pill or prying another slobbery piece of mulch from their puppy’s mouth.

      There’s still a lot scientists don’t know about animal taste preferences. But, thanks to a small but growing body of research, researchers are starting to unravel some of the mysteries around our four-legged friends’ flavor fancies. Here’s what we know so far.

       Accidentally drop a cupcake on the ground and your dog will probably scarf it down in one bite. Your cat, on the other hand, may turn up her nose. One possible reason for their ____________ behaviors? Cats can’t taste sweetness.

       Since they couldn’t just ask cats directly, researchers figured this out by analyzing their DNA. House cats, tigers, and cheetahs have a “broken” version of the gene Tas1r2, which works with another gene, Tas1r3, to enable sweetness detection. Though Tas1r3 appears to function perfectly fine in cats, Tas1r2 is an “unexpressed pseudogene” that’s missing 247 letters. Without them, Tas1r2 does not produce a crucial protein needed to form a receptor for sweetness on cats’ taste buds.

       To take the study a step further, they gave 25 felines the choice between a bowl of plain water and one that’d been spiked with molecules that provide umami flavor. As ___________, the cats strongly preferred the umami water, and more specifically, water containing umami compounds present in tuna. That may help explain why felines love the saltwater fish so much.

        EAL classrooms are spaces to build communicative competence in the English language. That language has a unique role for many people around the world. For those without financial resources who do not live in English dominant countries, the digital sphere is perhaps the only space in which authentic use of the language is likely to take place. For learners situated in inner circle countries, effective use of the language can make the difference between social, economic and political exclusion, or inclusion. This is also true for a lesser extent in outer circle countries. For those in expanding circle countries, English is becoming a language of the global elite in political, economic, and academic life. In all of these circles, it is often used as a lingua franca. Sociocultural theory states that true competence in encoding and decoding language can only exist when there is an understanding of the cultural realities attached to the communication when it is used. Digital media provide the vector of communication for a tremendous number of communicative acts in all of the circles, but communication in the digital medium carries special attributes that are not necessarily obvious or transparent. Therefore, it seems imperative to arm language users with an understanding of communication issues the digital realm as well as an understanding of the implication of communication in this space. Furthermore, there is an ethical responsibility to empower language users from a variety of background with equal agency and therefore equal voice. Doing so requires more than just technical skills, but also skills of critique and critical language awareness, productive ability, and an understanding of agency and rights claims that stretch from the linguistic to the economic and political. By reimagining Critical Language Awareness as a component of a multiliteracy approach that encompasses the full spectrum of analogue to digital communication in English, teachers, students, and policy makers can work toward making language studies as relevant, authentic, and empowering as possible.
