I know it's very cruel but very heart pain to see him suffer rike tish.
he can still eat, quite well in fact but it no longer have the physical ability to move around much.
he keeps his head down cause it's too tiring to lift it up and cause of tht, he'll constantly unbalance, falling on his back with all four legs up and he'll need help to get up again.
he's weak in many areas, further more 1 of his balls is very swollen, so i guess it's very painful to him
PS: not my pet, asking for others. he's a rabbit, 13 yr old liao
better not to let it suffer further?
Sorry, i dont prefer you put it down.
let it go naturally.
Leave it to nature.Killing him would bring you bad karma.
