I love Ms. Meyer's products!!! Wegman's sells all of their stuff, from cleaners to soap to lotion and everything else. It's all entirely plant-based, most of the cleaners contain only Deionized Water, Decyl Glucoside (sugar used as a surfactant to remove dirt/grime), and then Polysorbate to break-down oil and grease...Some of them also contain different plant extracts that are also used to break-down grease and dirt...But every single product they make contains only Water and then fully natural, plant-derived products, such as sugar and Polysorbate. Totally safe for birds, depending on the SCENT...
I don't buy the Pine scent, but any of the other "scents" are fine...They are so subtle that you can't really smell them for long anyway, like the Radish scent, the Lemon scent, the Peppermint scent, I forget the rest of them, but they are all either herbal scents or plant scents...I use them all except for the Pine...Great stuff.
