Here are some ideas:
Large Cats:
* Lion: Lions are the largest of the wild cats and have a very distinctive mane on the males.
* Tiger: Tigers can grow very large and have striking stripes.
* Jaguar: Jaguars are powerful cats with distinctive rosettes (spotted markings).
* Leopard: Leopards are smaller than tigers but still large and have beautiful rosettes.
Fox-like:
* Red fox: While not "huge," red foxes are common and may seem large compared to house cats.
* Arctic fox: These foxes can be quite large and have a fluffy coat.
* Fennec fox: These foxes have huge ears and can seem quite large, especially compared to other fox species.
Other possibilities:
* Lynx: These large wild cats are known for their tufted ears.
* Bobcat: Bobcats are smaller than lynxes, but still quite large. They have short tails and can look fox-like.
Could you give me more information about the animal you have in mind? For example, where did you see it, what color was it, and what was its approximate size?
