What is needed at that time is a rational basis for a decision. Some diseases, including cancer, can be treated, offering a measure of life extension. In such instances, euthanasia is not the only alternative. Other conditions, such as renal failure , congestive heart failure , or some forms of metabolic disease, may offer no hope at all. Euthanasia then becomes the only humane consideration.
Pets offer companionship, emotional intimacy, and feelings of well-being to their caretakers.
Humans should create happy, pleasurable lives for their pets. When well-being turns to suffering, alternatives should be considered. As long as an ailing animal is enjoying life without pain, there is justification for his continued presence. The quality of life, not quanitity of life, can help the owner determine the cat's reason for living. Euthanasia is a nearly painless process.
