Why is my cactus losing its spikes?
I got the cactus a few weeks ago, and it's been growing really well. But the thorns on the new flesh all just fall off as it gets taller. What's causing this? And will they grow back? Thanks for your time!

No, they will not likely grow back. This is usually caused by a lack of light. Almost all cacti need bright full sun. If they are not receiving this, then they will show signs of stress such as this. Move this to a brighter location, and give it a larger pot. This small pot is for decoration, and is not intended to be the final home of the cactus or, in most cases, is only eant to live for a very short period.
