Cactus garden!

Ferocactus emoryi

 

My cactus knowledge is to say the least poor, thanks for the correct IDs Pete.
I was just going to snip the very ends of three spines off, maybe a mm or two.
I will split them probably next year.

 

I once had a cat who would snap the ends off the spines of my Ferocactus. In the end I put it out of her reach incase they damaged here eyes.

Your Rebutia could possibly be R. heliosa 'sunrise' . I used to have one, they flower easily and are very pretty.

 

I have recently seen a video of a Big Horn Sheep in the US head butting a ferocactus, smashing it in half, eating the succulent insides and then spitting out the spines, must have a tongue made of leather!!!

 

I saw a video of two big horn sheep having a bit of a fight.
I dont know what the horns or skull is made of but you wouldn't want to get in the way of one of them.
