Castor oil is darker, thicker and higher viscosity. Canola is more of a pale yellow and thin. If it wasn't canola (which I assumed it was because it's the cheapest) it was some other cheap filler. Point being, I no longer trust amazon to send me anything that's going on or in my body. Then when we got a fake birdfeeder I realized there were a ton of fake products on there.

We weren't the only ones to get a fake birdfeeder, fwiw:

> WARREN, R.I. (WPRI) — Aspects has been in business for decades, manufacturing bird feeders that come with a lifetime guarantee. So in 2016, when a customer called about a defective hummingbird feeder, the Warren-based company took the complaint seriously. “We went through the process of cutting the plastic and looking at all the different molding telltales and we realized it was not our product,” Trisha Torres, the CEO of Aspects, told Call 12 for Action. Torres said the product was a counterfeit. She knew if there was one, there had to be others.

> “We found that it was just rampant on Amazon,” Torres said. In 2017, U.S. Customs and Border Protection seized 3,828 counterfeit Aspects bird feeders in 68 cartons. Federal court records show Aspects won a permanent injunction against the LLC that made the shipment, but even now, Torres still finds fakes on Amazon. “My customer service department has fielded hundreds of these calls,” Torres said. “People’s knee-jerk reaction is they are just angry at us. They think we’re not standing behind our product.”

You can't tell from the odor?
