There are two ways to give your cat or kitten nose drops. Spoiler: neither of them involve using the bottle. It is almost impossible to get the drops into the nose with it. Instead, I recommend using either a q-tip or 1mL syringe.
Q-Tip Method
This is probably easier for beginners. I couldn’t find the video that taught me, but this seems like a good alternative. The instructions start at the 3-minute mark.
Syringe Method
This is my favorite method. If you get the drop just right on the syringe, it will fall into the nasal cavity when you touch it to the nose.
