I gave it to him the first day (two different syringes) I was holding him down. while I tried to hurriedly inject it into his cheek. He spit most of it out and was foaming at the mouth.
I gave up for a couple of days.
I was frustrated and cursing the fact there might have been a one time injectable that would have saved me from this task twice a day for two weeks.
Yesterday I tried sitting on my legs with him in between but he just worked his way out the back.
What I didn't count on was our trust in each other.
This morning (after I cussed at him for not taking his medicine) I had the two syringes ready) I picked him up in my arms like you would normally carry a cat while you're walking across room and he was facing my chest and with the hand of the arm I was supporting him with, I grabbed the scruff of his neck gently and was able to inject both of them with my other hand without a fight or being clawed to shreds. (I was only wearing a T-Shirt and I don't cut his claws because he goes outside every morning.)
Third option worked. First two didn't.
This is what you have to do when you quit smoking, find the right option.
