Euthanasia is a serious and sensitive issue that should only be performed by a qualified veterinarian.
It is illegal and unethical to euthanize an animal yourself.
If you are considering euthanasia for your cat, please reach out to your veterinarian or a local animal shelter for guidance and support.
There are other options available, such as finding a loving new home for your cat or seeking alternative forms of treatment.
Please remember that your cat deserves humane and compassionate care, and seeking professional help is the best way to ensure that.
