I have graves all over my garden. Numerous rabbits, guinea pigs, hamsters and a huge Koi. which still bears a cross marking its grave. My son was so upset when it died. Also have a snake, Prucilla, bought by same son but who, without me, would never have survived (the snake)! I used to have to keep mice in my freezer to defrost and feed her. The things you do for children. (Note, did not use the term 'kids').
I will not get started on cats except to say that I detest the ginger tom who lives next door. My garden is his territory. He has ruined where all my alpines are planted, despite me putting rose cuttings down. 'Nuff said.
