i'm worried my 7-year-old lop is on his last legs here. over the last couple days he's had multiple seizures & each one seems to result in him losing more control of his limbs. he can barely push himself around on his back legs, his front paws work intermittently, & he's seemed a little more out of his head after each one. i've never had to witness any of my pets dying before, and we dont want to take him down to the vet to euthanize him as the car ride would likely give him a heart attack, so if this is the end of the line for him i'd really appreciate any suggestions on what i should expect. i know rabbits/bunnies can scream and spasm when they die, is that always true or is there any chance of him going peacefully?
