I know you're onto something here donnamt.
I watched the forum for maybe 2years before I joined, waiting for an answer for Thumps so I could contribute something. I noticed seasonal variation too.
I could put your figures out on the poll, because of his illness.
For us winter is the worst Nov, Dec, Jan, Feb, March, (wild plants which help gut motility are unavailable) It's so bad, I panic every winter "how can I get him through it this year?"
Summer heat is next: July, August, Sept.
Please help Donnamt everybun. She needs all the info she can get.
