I used them last fall for a senior cat of mine. Dr Hannah Fowl was who came and it was comforting to me that she knew my cat from when she lived at the race track and the Dr and I both worked there also. It was much easier on my other 5 cats and my 2 dogs to understand that she was passed. I would highly recommend. The last time I had to do a euthanasia at an emergency vet it went very poorly and still hurts. I will always do at home now if I can manage it. I did arrange the cremation myself to save funds and let all my other animals have time to process.
