One of my guineas 'Charlie' has developed a limp today - kind of a hobble, difficult to see which leg limpingon so i have caught her and checked all her feet and they all look ok, i have never cut her nails inthe last yr as they are always out and they never seem that long. Anyway she is seeming happy enough and still lawn mowing my lawn as i type, shoud i see how she goes or take her to the vets?
