We use nail caps on two of our four cats (not always the name brand, just whatever is cheapest usually).
The glue that comes with the package seems a lot like super glue (it gets on our fingers "occasionally"), but it doesn't stay in liquid form for very long once the tube has been opened (I suspect because it doesn't have a very tight sealing lid).
The cats tend to loose 2-4 caps a week, and it would be nice to be able to replace just the handful of caps without the tube of glue drying out before the next time we need to use it. They sell extra tubes of adhesive, but it drastically increases the cost of using the nail tips to use a new tube of adhesive every few days.
Since the nail cap adhesive seems to have similar properties to super glue, is it safe to use super glue to replace a few caps at a time? Or is the nail cap adhesive a special non-toxic formula that only ACTS like super glue?
