Cat Litter and Litter Boxes
To Clump or Not to Clump continued...
The variety of clumping litters offers several options beyond the
traditional scented and non-scented choices found with most granulated litters.
Most cats prefer non-scented litter, an especially important point for owners
who plan to use covered litter boxes. There are multi-cat formulas that form
more cement-like clumps that will keep their form even when tread on by extra
cat traffic; these are definitely not flushable! There are also less-tracking
formulas, which offer slightly larger granules that are more likely to fall off
of the cat’s paws before he leaves the box. And there are clumping litters
developed especially for flushability, a quality most clumping litters don’t
have due to their expansive properties. Each year the list of varieties
A few years after clumping litter first came out, an article in the
now-defunct holistic cat magazine Tiger Tribe questioned the
safety of clumping litter if ingested, especially for neonate kittens who often
eat litter when it is introduced to them during the weaning stage. While there
has been no proof to claims of problems in scientific literature, caretakers
may wish to delay introducing kittens to clumping litter until 3 to 4 months of
age. Any cat older than that detected eating litter should be taken to a
veterinarian, since this behavior often indicates anemia or other dietary deficiencies.
Scoopable cat litter continues to be a hot topic on the Internet, with some
claiming that it is toxic and causes respiratory illness in cats. Many
scoopable cat litters contain bentonite clay, a naturally occurring clay
mineral that is considered to be biologically inert when ingested, and/or
silica. Silica is also a physically and chemically inert substance, and is a
major component found in ordinary sand. Silica is also used as a
moisture-absorbing agent in the little packets found in shoe boxes, medications
and some foods. According to our experts at the ASPCA Animal Poison
Control Center, pets ingesting small amounts of silica gel may develop only
mild gastrointestinal upset, if any signs develop at all.
Cats may ingest small amounts of litter when grooming themselves after using
the litter box, and these amounts pass through the digestive tract easily
without problems. However, if an animal consumes a very large amount of litter
(as can happen when a dog "cleans out" the litter box), gastrointestinal upset,
constipation or, in rare cases, intestinal obstruction
could potentially occur.
The field of cat litter doesn’t end at granulated vs. clumping clay. The
shelves at local pet supply emporia also hold an array of litters made from
eco-friendly materials, including recycled newspaper, corn cobs, peanut shell
meal, processed orange peel, wheat, pine sawdust and shavings, and hardwood and
cedar chips. All promise to be superior odor controllers, long lasting and
earth-friendly. What to choose, what to choose...?
