Implicating shrew → mammal
Link to implication

Reason:

We have 100+ content of the shrew itself, I'm surprised shrews haven't been implicated as mammal. I'm not implicating as rodent, as despite appearances they aren't rodents. and are actually more closer related to moles.

Regardless, this species needs a mammal implication.

Other species related aliases

• bengal → bengal (disambiguation) - several species have the siberian prefix.
• bengal cat having an implication to cat would be great too, but I didn't suggest it because the tag isn't as widely used but I figured eh, I'll put it here.
• djinn → genie
• golden cat → golden cat (disambiguation) - Multiple golden cats, african and asian more specifically.
• nine tailed fox → fox - seeing as how kitsune is aliased to fox, I don't see why this isn't either
• saber tooth cat → saber-toothed cat - common misspelling
• saber toothed cat → saber-toothed cat
• siberian → siberian (disambiguation) - many species have the siberian prefix.
• south chinese mountain cat → chinese mountain cat - official name is the latter
• implicate to feline as well; it's a wild cat
• spinosaurus → theropod
• tabby → tabby cat (or reversal; I'm mainly suggesting this since the latter has implication to cat, but we could do that for plain tabby too)

Other species related implication changes/removals

• Remove pallas's cat's implication to cat; it is a wildcat, not a domestic cat. Add feline implication instead.

There are many more tbh but... Might be better to start small and not go too overboard in one post.
