If there&#8217;s one thing you can be sure of, it is that cats will lick themselves after using the bentonite clay because this clumping variety of litter will stick to their paws. Every time your pets visit the litter box, they ingest the cat litter through inhalation and licking.<\/p>\n<p>The litter accumulates in their stomach and swells, forming a hard lump that renders the stomach to the same state as blocked plumbing. The body will try to cleanse itself through repeated bouts of diarrhea during which time the stomach can hardly absorb any nutrient.<\/p>\n<p>Unfortunately, only the diarrhea is diagnosed by most doctors, and medicines are prescribed upon such diagnosis. The patient eventually succumbs to a very painful death.<\/p>\n<p>The only treatment is to remove the cat from the litter, and then to put the patient\u00a0on holistic treatment using soothing laxatives to get rid of the poison. During this time, it is best to feed homemade chicken or fish broth or stock. If the treatment begins early, recovery is a distinct possibility.<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-1549 size-full\" src=\"http:\/\/kapush.org\/cat-litter\/wp-content\/uploads\/2017\/05\/Get-notified.gif\" alt=\"Get new post notification ...?\" width=\"300\" height=\"200\" \/><\/p>\n<p><!-- Begin MailChimp Signup Form --><\/p>\n<style type=\"text\/css\">\n\t#mc_embed_signup{background:#fff; clear:left; font:14px Helvetica,Arial,sans-serif; width:100%;}<br \/>\t\/* Add your own MailChimp form style overrides in your site stylesheet or in this style block.<br \/>\t   We recommend moving this block and the preceding CSS link to the HEAD of your HTML file. *\/<br \/><\/style>\n<div id=\"mc_embed_signup\">\n<form id=\"mc-embedded-subscribe-form\" class=\"validate\" action=\"\/\/kapush.us13.list-manage.com\/subscribe\/post?u=5daf7df30d4da02519aa485ab&amp;id=76fc6fe0be&amp;SIGNUP=Bentonite\" method=\"post\" name=\"mc-embedded-subscribe-form\" novalidate=\"\" target=\"_blank\">\n<div id=\"mc_embed_signup_scroll\"><label for=\"mce-EMAIL\">Be notified when we publish new posts?<\/label><br \/>\n<input id=\"mce-EMAIL\" class=\"email\" name=\"EMAIL\" required=\"\" type=\"email\" value=\"\" placeholder=\"email address\" \/><br \/>\n<!-- real people should not fill this in and expect good things - do not remove this or risk form bot signups--><\/p>\n<div style=\"position: absolute; left: -5000px;\"><input tabindex=\"-1\" name=\"b_5daf7df30d4da02519aa485ab_76fc6fe0be\" type=\"text\" value=\"\" \/><\/div>\n<div><input id=\"mc-embedded-subscribe\" class=\"button\" name=\"subscribe\" type=\"submit\" value=\"Send Occasional Updates\" \/><\/div>\n<\/div>\n<\/form>\n<\/div>\n<p><!--End mc_embed_signup--><\/p>\n<h2>Types of Cat Litter<\/h2>\n<p>Currently, apart from the organic varieties, there are three main categories of cat litter: clump,<strong> <a title=\"CAT LITTER PROBLEMS WITH SILICA GEL CRYSTALS\" href=\"http:\/\/kapush.org\/cat-litter\/silica-gel-cat-litter-problems\/\">silica crystal<\/a><\/strong> and the plastic crystal varieties.

D. Shojaim, <em>How Cat Litter is Made <\/em>in its October 1994 issue<\/a>.\u00a0The following is an extract:<\/p>\n<blockquote><p>&#8216;Sodium bentonite, a naturally swelling clay, is often added as an extremely effective clumping agent. When liquid is added, bentonite swells to approximately 15 times its original volume. But because sodium bentonite acts as an expandable cement would, litters containing sodium bentonite should never be flushed; when they expand they can block plumbing.&#8217;<\/p><\/blockquote>\n<p>Curiously enough, the article made\u00a0no connection between possible internal blockage that a living being may develop if sodium bentonite litter is ingested. Perhaps, the author did not take into account the possibility that cats could accidentally (while grooming themselves after having visited the litter box) or willfully (as is frequently the case with kittens) ingest this litter.<\/p>\n<h2>Voices\u00a0of dissent against sodium bentonite clumping litter<\/h2>\n<p>Marina McInnis, in the January\/February 1995 issue of <em>Tiger Tribe: Holistic Health &amp; More For Cats <\/em>writes about a mysterious disease that kept plaguing (and often killing) her kittens. She finally connects the symptoms to the clumping litter and replaces it with an organic litter. The patients are finally cured through holistic medication.<\/p>\n<p>An updated version of her story may be found <a href=\"http:\/\/www.thelighthouseonline.com\/articles\/clump.html\" target=\"_blank\" rel=\"noopener noreferrer\">here<\/a>.\u00a0\u00a0In her write-up, she refers to Shojaim&#8217;s article in Cat Fancy magazine. She also has archived on her site hundreds of letters from cat owners thanking her for saving their cats&#8217; lives through this one article.<\/p>\n<p>But of course, those letters are not scientific evidence and neither is her &#8216;story&#8217;.<\/p>\n<p>It may be pertinent to note in this context that <a href=\"http:\/\/www.thelighthouseonline.com\/articles\/hornfeldt.html\">clinical evidence<\/a> of (suspected) bentonite toxicosis in a cat is published for the first time in the public domain by Marina as well.<\/p>\n<p>May 2000, Annie B. Bond&#8217;s <a href=\"http:\/\/www.care2.com\/greenliving\/the-dangers-of-clumping-cat-litter.html\">article<\/a> appears on Care2.Com: The Dangers of Clumping Cat Litter.<\/p>\n<p>Stanford University&#8217;s eco-advice column <a href=\"http:\/\/ecoadvice.stanford.edu\/digging_deeper\/dd_litter.html\" target=\"_blank\" rel=\"noopener noreferrer\">answers a query in December 2007<\/a> on choosing cat litter.

I could not find its date.<\/p>\n<p>In late 2011 I started this blog on my earlier domain kapush.net.<\/p>\n<p><em>This list is more of a chronology leading to my own efforts than a &#8216;Further Reading&#8217; section and is by no means exhaustive.<\/em><\/p>\n<h2>The number one reason clumping clay litter is considered safe<\/h2>\n<p>Dr. Elsy&#8217;s <a href=\"https:\/\/drelseys.com\/about\/faqs\/\">sums this up<\/a> with much confidence (under &#8216;Precious Cat Litter&#8217;, Question: &#8220;Are clumping litters safe for my cat?&#8221;):<\/p>\n<blockquote><p>Concerns that bentonite clays will \u201cset-up\u201d in a cat\u2019s stomach are un-founded [sic]. Over half of the litters sold today include bentonite clay and have proven safe for cats since their introduction over fifteen years ago. In fact, the convenience of clumping clays have [sic] contributed greatly to the growth of cats as pets. In Dr. Elsey\u2019s 25 plus years as a feline only veterinarian, he has never had a case where clumping litters have caused a problem with a cat.<\/p><\/blockquote>\n<p>In other words, there is NO EVIDENCE that sodium bentonite clumping clay litter may be harmful to cats. Anecdotal evidence, of course, doesn&#8217;t count.<\/p>\n<p>Interestingly, Dr. Elsy&#8217;s says the following to the question &#8220;Are your litters flushable?&#8221;<\/p>\n<blockquote><p>No! DO NOT FLUSH our litters. These litters are designed to form hard clumps. A \u201cflushable\u201d clumping litter is a contradiction. If it dissolves or breaks apart in a toilet, it will break apart in a litter box. A true clumping litter is more convenient for you and better for your cat.<\/p><\/blockquote>\n<p>Cat&#8217;s Pride (a flushable litter that\u00a0<a href=\"http:\/\/catspride.com\/frequently-asked-questions\/\">claims not to clump as hard<\/a> as sodium bentonite litter) echoes Dr. Elsy&#8217;s in support of bentonite clay:<\/p>\n<blockquote><p>Any suggestion that sodium bentonite will cause harm or fluid retention in cats is simply not accurate and has never been documented in the veterinary scientific community. \u00a0In fact, numerous consultations, interviews, and tests by many vets have found no evidence relating normal use of a clumping\/sodium bentonite litter with the sickness or death of any kitten or cat.

Bentonite clay and other, similar ingredients found in inorganic cat litter have effectively stabilized and absorbed liquid nuclear waste for years. It is possible that sodium bentonite cat litter has absorbed more ammonia and urea from nuclear waste than it has from kitty pee (!). This came to light after an unfortunate incident at the New Mexico Waste Isolation Pilot Plant (WIPP). Workers had arbitrarily replaced the usual inorganic cat litter with <strong><a href=\"http:\/\/kapush.org\/cat-litter\/organic-cat-litter\/#scoopwheat\" rel=\"nofollow\">Swheat Scoop<\/a><\/strong> which is made from wheat. According to <strong><a href=\"http:\/\/www.forbes.com\/sites\/jamesconca\/2014\/05\/10\/nuclear-waste-leak-traced-to-kitty-litter\/#4eaabb1334ce\" target=\"_blank\" rel=\"noopener noreferrer\">James Conca<\/a><\/strong>,<\/p>\n<blockquote><p>Cat litter has been used for decades in radiochemistry labs and nuclear facilities to stabilize certain radwastes, like liquid scintillation solutions, evaporator bottoms, and other materials that have nitrate salts in solution.<\/p>\n<p>Nitrate salt solutions can ignite when they dry out \u2013 which is why it\u2019s tricky working with nitrate solutions in the\u00a0lab and why you need to make sure they don\u2019t dry out, something many a chemistry student has found out the hard way. So you need to stabilize nitrate solutions before they dry out, or prevent them from completely drying out.<\/p><\/blockquote>\n<p>The organic litter was not equipped to stabilize the nitrate salts and dried them to the point of ignition. Well, this was in 2014 and on Valentine&#8217;s Day, no less. Thankfully, there were no fatalities and the radiation released was not strong enough to cause environmental concern. WIPP, in spite of performing flawlessly for 15 years, was shut down after the incident and <strong><a href=\"http:\/\/www.wsj.com\/articles\/new-mexico-presses-ahead-on-nuclear-waste-plant-reopening-1456655406\" target=\"_blank\" rel=\"noopener noreferrer\">last I heard<\/a><\/strong>, it was supposed to reopen this year (2016).<\/p>\n<hr \/>\n<h2>Clumping is not the Problem<\/h2>\n<p>Cleaning the litter box and replacing used litter is made extremely convenient if the litter clumps. The problem, therefore, is not the property of clumping but the agent used.
