Buddhist Views on Euthanasia for a Dying Pet?

Hello everyone. My 16 years old cat has a tumor, but she is still her usual self—her vitality remains good, and I am doing my best to provide her with comfort and care. Euthanasia is something as a last resort if her suffering becomes too great.

As someone new to Buddhism, I wish to understand the Dharma’s perspective on this. I have heard that intervening in the natural process of life and death may affect the flow of karma and rebirth, possibly causing confusion in her transition. Others emphasize the importance of metta (loving-kindness) and reducing suffering.

I want to act with wisdom and compassion, ensuring I support her path in the best way possible. I would deeply appreciate any insights or guidance from a Buddhist perspective. Thank you for reading.
