Sorry to hear that, I know how you feel, Our Mama Cat, along with 3 others were poisoned back in the winter, and we had to watch them suffer and die, took one to the vet, $500.00 later, said there was nothing they could do, put him to sleep, the other 3 we gave valium to let them go in peace. They are great pets, and you get love them like kids, and it hurts to watch them suffer or die.
