It’s a prickly fellow. Very sharp needles.

Once neglected however he’s survived! He’s growing wider rather than upwards. Easy to look after and probably the easiest cactus I’ve repotted due to lack of spikes!

I've had this cactus for about 5 years and he's still going strong. I've never repotted him and left him without water for weeks at a time before and he's had no issues at all, extremely low maintenance and very cute :) I now water him once a week or so and he's doing just fine
