Vermin Companions

[Drake Brimstone]

So, there are a bunch of nifty magic items out there intended for Animal Companions or just Animals that travel/fight with you without being bonded.

Vermin however are not "Animals" their type is "Vermin"

Can a Vermin use an item such as a War Saddle, or Bridle of Tricks on their Vermin Companion? (Assuming it has the slots for such items.)

If not, what if their Int is increased to 1+ do they then count as Animals?

[Weirdo]

They can't use them by RAW, though it's a reasonable house rule.

Increasing their Int using the ability score increase doesn't change their type (just like it doesn't turn an animal into a magical beast).

[DJEternalDarkness]

I allow it as a house rule (as the druid in one game has a mantis).
