Or you can install Xenobionic Patcher (along with Cyber Fauna) and it'll work for everything.

I have an interesting idea.
While I like the idea of "same implants for all animals" I also dislike that rats and thrumbos require same investment (not to mention modded monsters like Summit Crabs)

So I came up with concept of modular implants and surgeon/vet not simply installing implant, but puting modules together and building limb/organ on the spot.
It would even simplify mod a bit and number of different items would be decreased.

So here is my basic idea explained best I can

Limbs

Animal Prosthethic Kit (operation also needs steel&synthread)
Mini hidraulics with basic neural interface

Jaw-2kits+5steel+5synthread
Leg-3kits+10steel+10synthread
Spine-5kits+20steel+20synthread
(numbers are pulled out of my ass :) BTW, feel free to adjust them)

Animal Bionic Kit (operation also needs plasteel&hyperweave)
Synthmuscle bundle with advanced neural interface

Jaw-2kits+5plasteel+5hyperweave
Leg-3kits+10plasteel+10hyperweave
Spine-5kits+20plasteel+20hyperweave

Animal Archotech Kit (operation also needs chemfuel)
Ultratech animal bionic core, uses chemfuel to synthesise artificial flesh, superior to original in every way.

Jaw-2kits+10chemfuel
Leg-3kits+20chemfuel
Spine-5kits+40chemfuel

Boosters

Animal Subdermal Plate (yes one item, but can be installed in different places)

head-2plates+10hyperweave
neck-1plate+5hyperweave
body-5plates+30hyperweave

This is core numbers
But exact kit number and resource amount (and medicine used) scales by core numbers being multiplied by animal size (rounded with minimum 1)
Same with eyes and organs (number gets scaled by size and rounded)

So armoring rats head (size 0.15) would requires (2*0.15=)0.3 Animal Subdermal Plates and (10*0.15=)1.5 hyperweave, but it all rounds up to 1 plate and 2 hyperweave (plus scaled medicine)

That way items could be the same but used in different numbers based on size.
Did I explained it clear enough or does this look like ramblings of madman to you?
