I've got long haired piggies and their coat is very woolley, similar to angora (they are alpacas) - when it's about 3" long (after 2 months or so) I cut it all off very short, just a tuft at a time starting at their head and working down one side of their body then turning them around and do the other side, and lastly check under their 'leg pit' for matts (which they don't usually have at that stage, but some are better at grooming themselves than others)
I leave it half an inch long or less, mostly you can see their skin it's so short, using a small pair of round ended hairdressing scissors - I did 4 piggies yesterday (none matted) and ended up with a pile of wool as big as a football :shock: 3 pigs took me 5 mins each, but the other took a good 20 mins as he tried to bite me the whole time and wouldn't sit still for a second :roll: I used to take a lot longer doing it but I just whiz along now - I'm sure it's quicker to keep it short with scissors than use clippers on long hair - if your animal behaves that is :?
I think Adele has a lot of angoras - maybe ask her?
