The subject of Freya's cats came up recently on social media, so I wanted to share this excerpt from my forthcoming book Pagan Portals Freya. I hope this may clarify some points, as this summarizes the information we have from the older sources and may help people differentiate between new ideas and stories and the older beliefs.
Cats – Freya is said to travel in a chariot pulled by two cats, probably wild cats. The Grimnismal doesn’t tell us or even hint at what kind of cats they may be, saying only “Whenever Freya travels, she sits in her carriage which is drawn by cats”. The Skáldskaparmal refers to them as ‘gib-cats’ an antiquated term for male cats, possible neutered. The actual term used in the original language for the animals is vague and they have been depicted in art as everything from small house cats to wild cats, although in modern folklore and belief they are usually envisioned as large cats.
Her ownership of these cats has been the source of much speculation among scholars. O’Donoghue suggest they may represent chaos as a chariot pulled by cats would seem to be a difficult option. Turville-Petre sees the cats as representing lust, saying: “The cat, as the Norse pagans must have known, is the most lascivious of beasts.” (Turville-Petre, 1964). Ellis Davidson takes the most benevolent view and ascribes the cat association to Freya’s connection to seidhr and the cat’s reputation as a supernatural animal.
In the older sources these animals are never named, however Diana Paxson in her 1984 novel ‘Brisingamen’ chose to name the cats Bygull (Beegold) and Tregull (Treegold) as modern poetic kennings of Honey and Amber. These names have gained popularity across modern pagan books and can be found in several such texts given as if they are the original mythic names of the cats.
While it is generally assumed today, and has been across artwork for many years, that the cats are indeed cats there is some question around the original word used. Older translators have no hesitation to give the word as cats or tom-cats, but Grimm in Teutonic Mythology questioned whether bear wasn’t the intended term and an assortment of other animals, including weasels, have also been suggested. Despite this there is reasonable evidence that some form of either wild or domestic cat was meant and would have been understood by the contemporary audience.

 If one can ever be said to own a cat
 I was told that this was a personal choice in an online correspondence with the author, however it is also publicly referenced in Our Troth, vol 1, page 373.
