Here's the three-week old cactus given to me by Br. Itchan before he left for the States. I'm sure, it's more than three weeks, but my counting started when I received it.
I'm totally clueless as to how to take care of a cactus, but looking at his stable growth (of the spikes, that is) and the vivacity of its green, I guess it's still alive.
In this photo, I mounted a (lifeless) moth on its head for a more theatrical macro shot.
Oh by the way, let me call
it him Spikey.
