I cannot be positive there are worms in the poop, but it looks like a cecal poop which happens every so often. Safe Guard can be used once and in 10 days to get round worms, and it can be used for 3 days to get those, cecal, and gapeworms. Use it for 5 days straight to get the more rare capillary worms. Dosage is 0.25 or 1/4 ml per pound of weight, so weights might be good. I use Valbazen 1/2 to 3/4 ml given once and repeated in 10-14 days to get all worms. You could also try getting a fecal float done on some fresh droppings to identify worms, their eggs, and what types.
