Meaning

  1. cat
    Quorum inbutae mentes pravitatis erroribus quamvis carnificinam prius subierint quam ibim aut aspidem aut faelem aut canem aut corcodillum violenti quorum etiamsi inprudentes quippiam fecerint, poenam nullam recusent.Their minds being tainted by pernicious opinions, they are ready to bear any torture rather than hurt an ibis, a snake, a cat, a dog, or a crocodile; and should any one inadvertently have hurt any of these animals, he will submit to any punishment.c. 45 BCE, Cicero, Tusculanae disputationes 5.27
    Ut feles quoties fugitat, male pedere sueta est.Whenever the cat runs away, she is accustomed to fart badly.1528, Desiderius Erasmus, Adagiorum opus, page 773:

Origins

Unknown; maybe cognate with Welsh bele (“marten”). Other sources say that it is related to Latin fulica, fulix, with the etymological meaning of "animal with a shiny coat", but this theory is doubtful. The connection with Latin fēlix (“happy”) and Latin fēllō (“to suck”), with the (hypothetical) etymological meaning of “animal that sucks the blood [of its prey]”, was also proposed. This word could be cognate with Latin mēlēs (“badger”), under the assumption of a very unusual alternation of /f/ (or earlier */β/) and /m/, which might be an indication of substrate origin.
