"So sad when animals die during fire, much better when they're anally and vaginally electrocuted and their skin is ripped off their bodies (sometimes even when they're conscious!) for nothing other than your vanity!"
After the post began to gain traction from other KUWTK fans, Khloe responded insisting the coat was faux fur.
"I am wearing a Halloween costume. It's not real fur. But keep spreading your vile hate instead of focusing on real issues," the reality star commented. "Why must people assume and attack so quickly? You have some clear frustrations darling and they are completely misdirected. My advice to you would be, don't attack people in general."
She added, "But if you choose to waste your energy on attacking a complete stranger then at least know all of your information prior. Happy 2020."
It was then the fan then quoted the designer, who admitted to the coat being made with real mink and fox fur.
Daniel Leather, the designer, wrote: "@khloekardashian came to me with this vision i knew it will not be an easy task but i am so glad that the final product came out perfect."
He added the hashtags, "#shearlingcoat #shearlingjacket #sheepskinjacket #shearlingvest #furparka #foxponcho #furcollar #FoxCollar #Motojacket #KidsShearling #Fox#Mink #Sheep #kidsmoto #shearlingcoats #coatgoat #kidsleatherjacket #kingoforchardstreet #furparka #furrierofthestars #furrierofthecelebrities #celebritystylist #cashmerecoat".
This comes just hours after Khloe and sister Kim were forced to publicly confirm that they have donated to the Australian bushfire crisis amid backlash from fans.
The famous duo came under criticism this week for sending their thoughts to the country via social media without seemingly contributing funds.
But Kim was quick to defend her family when a troll posted a now-deleted tweet which read: "Nothing gets me more heated than to see the Kardashians/Jenners talk about climate change/wildfires and not donate even a penny."
In response, the mother-of-four wrote: "Nothing gets me more heated than to see people think they know what we donated to and to think we have to publicise everything."
