I've just attempted to measure Angel, who is sprawled across my table.
He wasn't completely stretched out, more relaxed, and had his tail curled around too; but roughly, from nose to bum he is a smidge under 60cm, then add his tail which is a bit over 30 cm.
Earlier I saw him standing at attention by the big flowerpot and noticed his ears were above it by about 5cm, so I went out later to measure that distance. When standing with head held up listening, from ground to ear tip, Angel is close to 40cm high. I'm not sure about ground to shoulder measurement.
No wonder he takes up so much space when he is stretched across my bed or table.
