hi! I've been following you for a while, and i remember at one point you listed guidelines for when it's time to euthanize a pet, or when it's not really humane to keep them alive. i believe two of them were when they can no longer eat or defecate on their own? would you mind sharing the rest of them again?
My *personal* guidelines for euthanasia-for-terminal-illness (what I have used for my own animals) include:
Wanting and able to eat, wanting and able to drink, ability to maintain a body condition score of 4 or above, ability to breathe without difficulty, ability to get up and walk unassisted the majority of the time, still wanting to interact to a somewhat normal-for-them degree, not extremely lethargic, normal-for-them mentation. I weigh and judge based on all these categories.
For other things, what's important to *me* is the ability to Cat or Dog or Snake or Guinea Pig or Rabbit etc... they need to be able to do normal things for their species. There are accommodations that can help with things of course and those should be used when useful. But the ability to eat and drink on their own is a big one for me. The ability to get away from their own waste, even if it's by 'dragging' themselves away. The ability for an owner to keep them free of pressure sores and urine or fecal scalds is also paramount. But they need to be able to do something other than lay there immobile for the majority of their day.
