This used to be my guinea pigs favourite hay, it was fresh, long strand and almost dust free, so I bought the big bales. Since then, the quality of the hay has DRASTICALLY declined. I’m sad to say just how much dust and debris I found in recent bags. What I received last was 24kg of green powder, logs, sticks and leafs along with what appeared to be dung. Luckily ZooPlus helped me acquire a refund, their customer service is phenomenal & staff are exceptional. Not their fault at all.
