My rabbit Mittens was killed last week. He vomited in the evening after coming back from the garden, then about 9pm in his cage he started convulsing and fitting. I didn't know what to do, the vet was closed, so I just brought him onto my lap. I know in terms of humans you should never try to restrain someone fitting, so I just kept stroking him. Eventually he stopped, and slowly stopped breathing. Tried CPR to no avail.
I've been feeling really guilty. Had I known he was dying, I really should have put him out of his misery when it started. I can't get the images of him suffering like that out of my mind.
Yesterday, my neighbours told me that a few days before, he'd got under the fence and they'd seen him eat some of their flowers, so they laid down baited rodent poison where he came through. I would have happily put down wire mesh under the earth to keep him in our garden, but the fact that they didn't even come to us says to me that they just wanted him dead.
