Help! Mystery Poop in My Garden – What Could It Be?

Hey everyone! This is my first time posting here. I recently planted some direct sow seeds in my first-ever garden, which I'm super excited about. We built two raised beds that are 2 feet high, but when I checked the garden this morning, I noticed some disturbance in one of the beds. We have a lot of squirrels around, so I assumed they might have been digging for nuts. However, I discovered some bright yellow poop just under the surface! From what I found online, it seems to be the size of a dog's, but would a dog actually jump two feet just to poop there? I don't have any dogs, and the area has some strays, but I've lived here for a year and never found any poop in the yard before. Do you think the soil could have attracted it? I've got netting ready for the squirrels when the seedlings sprout, but will that really stop a dog? I'm worried that a person might have put it there too. Any advice would be greatly appreciated! Thanks, and please go easy on me! P.S. There's a photo in the comments if you're brave enough to look!
