It took several weeks, maybe upwards of two months, for it to work for my cat but he did eventually start walking normal again. He has been diabetic for nearly a year and probably on the Zobaline for 10-11 months. At this point, I am superstitious...I can't say for sure that it was or wasn't the Zobaline that helped or it was a combination of good changes but I still give it to him every day!
Just a tip, one time when I ordered it, they accidentally sent me the human Xobaline. I called them and they said it was fine to give him but they would send me the Zobaline for cats. Three days later, he was very ill with BGs out of control. Turns out, I should have read the label VERY closely. One of the ingredients in the human form is glucose. I was seriously giving my poor diabetic cat sugar!!
I've also found that if LifeLink is out of stock, to go to Amazon and buy it there. I've always had success getting it.
