I’m confused, yucca is a completely different plant from cassava/tapioca...? Cassava is a tropical tuber, yucca is a family of desert plants. Joshua trees are yuccas.I read that Carrageenan, xanthan gum, cassia gum can cause inflammation in cats. Even worse is tapioca (tapioca is also known as cassava, yucca) and flaxseed or flaxseed oil because they cause cyanide in cat food and should never be allowed.
but unfortunately, we have no guarantee that what they add instead is any better. My boy has the same reaction to agar-agar as he has to carrageenan. And other gums don't necessarily sound any better. I choose gum free whenever possible, but there aren't many options unfortunatelyThankfully a lot of companies are realizing this and adding something else instead.
(corrected yucca should be yuca - sorry for mistake above)I read that Carrageenan, xanthan gum, cassia gum can cause inflammation in cats. Even worse is tapioca (tapioca is also known as cassava, yuca) and flaxseed or flaxseed oil because they cause cyanide in cat food and should never be allowed.
Rhian Cope wrote the chapter in Merck Veterinary Manual on cyanide in animal feed: flax is mentioned as one of the possible sources of cyanide from animal feed:
Overview of Cyanide Poisoning - Toxicology - Merck Veterinary Manual
Merck - Rhian Cope on cyanide from animal feed:
“Chronic cyanide poisoning: Goiter may be present. Cystitis ataxia toxidromes are characterized by opportunistic bacterial cystitis with or without pyelonephritis and diffuse nerve fiber degeneration in the lateral and ventral funiculi of the spinal cord and brain stem. Hindlimb urine scalding and alopecia may be present.”
“Chronic cyanide poisoning: Chronic cyanogenic glycoside hypothyroidism will present as hypothyroidism with or without goiter. Cystitis ataxia toxidromes are typically associated with posterior ataxia or incoordination that may progress to irreversible flaccid paralysis, cystitis secondary to urinary incontinence and hindlimb urine scalding and alopecia. Death, although uncommon is often associated with polynephritis. Late term abortion and musculoskeletal teratogenesis may also occur”
The following are links to articles on cyanide risks from flaxseed. Sweden banned its use. France banned flaxseed:
(PDF) Ground Flaxseed – How Safe is it for Companion Animals and for Us?
Warning: ground flaxseed can be toxic and shouldn't be eaten
I had my cat food that had ground flaxseed in it tested and it showed cyanide at twice the level that is safe for my cat that she had been eating for a few months.
This should not be allowed. FDA is not doing their job.
