Zobaline dosing for large cats

Diamond’s BG is going great right now. I’ve been giving him one Zobaline tab a day for two months for his neuropathy (all four legs). He’s getting a tad better. I know things take time to heal. I was wondering since he is 23 lbs now with an ideal weight of about 18 lbs, should I give him more?
I know he will pee out any extra his body doesn’t need/use. However, I don’t literally want to piss away money if giving him more won’t help. Anyone have experience with big cat Zobaline dosing?

 

I've been giving Rufus only 1 Zobaline a day, and he's 21.5 pounds. Someone mention this aleternative to Zobaline on FB https://www.amazon.com/gp/product/B008NIHCZC/ref=ox_sc_act_title_1?smid=ATVPDKIKX0DER&th=1. 2 capsules = 1 zobaline. You could give 3 capsules a day?

 

That’s a good methyl B12 (I use it as an extra source), but it doesn’t contain Folic Acid which is said to improve absorption.

 

Not sure giving more would help. If you didn't wanna do 2 a day you could try 1 in the morning and a half in the evening.

 

Thanks, I think I'll stick to one a day and wait it out.
