I am making a more reasonable cat, below is the template from Basic Set:
House Cat B263: A domestic feline, kept as a pet, familiar, or mouser.
ST 4 [-60]; DX 14 [48]; IQ 4 [-120]; HT 10.
(Note: No Fine Manipulators qualifies you to buy ST and DX with -40%.)
(A question here is, do I MUST by ST at -40% and get only 36 points back?)Will 11 [35]; Per 12 [40]; Speed 6; Dodge 10;Move 10.
SM -3; 10 lbs.
Traits:
Catfall [10] B41;
Combat Reflexes [15] B43;
Domestic Animal [-30] B263 (including Cannot Speak [-15]; Hidebound [-5]; Social Stigma (Valuable Property) [-10]; and Taboo Trait (Fixed IQ)
Night Vision 5 [5] B71;
Quadruped [-35] B263 (including Extra Legs (Four Legs) [5]; Horizontal [-10]; and No Fine Manipulators [-30]);
Sharp Claws [5] B42;
Sharp Teeth [1] B91.
Skills:
Brawling-16 DX/E [4];
Jumping-14 DX/E [1];
Stealth-14 DX/A [2].
(I do believe the book missed to add enhanced move [10] and +1 basic move [5], since the move is 10 not 6. Also the enhanced dodge [15], since the dodge is 10 not 9.)
Total points is -79 (or -49 if I am right).
================================================
On top of the template, I made the more reasonal cat the following way (the goal is to make a 50 point familiar):
1. I dropped enhanced move [10] and +1 basic move [5] and enhanced dodge [15], because it's not economic at all. This gives me 30 points back. (Total points: -79.)
2. I raised perception to 14, this costs 20 points. (Total points: -59.)
3. I took the disadvantages Curious (12 or less) [-5], Laziness (12 or less) [-10], Lecherousness (15 or less) [-7], Sense of Duty: Master [-2] and 5 quirks. (Total points: -88.)
4. I took the growth package [33]: Growth 4 [16] + Striking ST 12[12] + DR 4 [4] +Sharper Teeth [1]. (Total points: -55.)
5. I still have 105 (it's good to be a cat!) to spend on advantages and skills. Working on this now...
(A second question is: Can I make a smart cat? Or even a talking cat?)================================================
Maybe we should limit ourselves to 25 points cats? That way, Lo Bo can have -12 points of disadvantages, and will have still have 68 points to spend...
If you rule that I only get 36 points back from low ST, then I have 44 points to spend...
