Easing piggy at end of life

Sorry for the upsetting first post, but looking for ways to ease our boy in what we believe may be his final days.

Tater is not our first pig, but has lived quite a bit longer than any of our other boys. He is not coughing, wheezing, or showing any other signs of a typical illness. Just really sluggish and not eating well.

I am considering getting him unflavored pedialyte, and otherwise just trying not to crowd him or leave him alone. Are there any suggestions for helping him go easy?

EDIT: At roughly 8 years of age, our sweet boy Tater, has passed away. As far as we can tell he went peacefully. We followed the recommendations of a warm towel, which he snuggled into in his final moments. We are all heartbroken, but understand he is at peace. It is my hopes that animals do go to heavan.

I would like to encourage you all to continue sharing advice, and feel free to recommend the thread elsewhere. I would also like to share Tater's story with all of you.

Tater was rescued by my ex's family, from a less than ideal environment. He fought with his cage mates so her family, in their infinite wisdom, decided they were going to just set him loose in the woods.

My niece begged my ex to take him knowing he wouldn't survive, and so she did. When she went to college with me my mom took her on. Sadly, after we both came home from college, my ex became a different person. Coldly indifferent to her supposed adoptive family, neglectful to Tater, verbally abusive to me, and physically abusive to our mini aussies Corkie and Lucy.

When all was said and done she went elswhere, and our sweet babies all stayed with us. Tater gained a few pounds with my spoiling mom, but he also became a much happier pig. He had food as soon as he wheeked for it, fresh water each day, and plenty of snuggles from my mom and brother (who adored him). He wasn't too fond of me in spite of our previous enjoyment of the other's company, but we had our moments. We are all pretty upset, but knowing he went on to lead such a good life against the odds he faced gives us a sense of peace.

Thank you all for the support. Its never easy, but just remember, the love you feel for them is why it hurts. And you love so that it hurts, you really made their lives great.
