Hello We have a pair of angora goats and are wondering if anyone can tell us how old is a good age for them? We have had saan goats before and they lived till 20 and 16 but we're thinking angoras aren't as sturdy... Their teeth have just started to come loose...they are 11 now. Also does anyone have any advice on if they need any special care in their old age? Any extra treats to keep them healthy? Doreen and Jane.
