August 2004 – March 2005:
I have found objects in Yesterday’s News (YN) litter that could scratch or puncture a rabbit’s skin, and others that could cause an impaction or an internal injury if swallowed. The objects, shown in the photos below, include what appear to be and what feel like:
- sharp, hard metal shards
- small pieces of metal foil
- hard shards of plastic
- hard plastic plugs up to 3/8″ long
- shreds of lightweight plastic up to 1/2″ long
Since I started carefully studying YN litter, every bag of it that I have purchased has contained staples and other sharp pieces. I have photographed the dangerous objects from only a few bags.
One of my rabbits has been eager to eat YN litter. Since I began seeing for myself the foreign objects that are in the litter, I will not let any of my rabbits run the risk of hurting themselves on, or ingesting, those objects, some of which are so sharp that they could pierce skin or internal membranes.
In a telephone conversation with a customer service representative at Purina, I learned that the 30 percent of the content of YN litter that is not post-consumer paper material is floor sweepings from lumber mills. The rep was unable to tell me what kinds of wood, or what other materials, might be in the litter as a result of the floor sweepings. But I prefer that my rabbits not have the opportunity to ingest such floor sweepings.
Because of the potential dangers, I use YN litter only with a grid on top of it so that a rabbit cannot reach the litter. Under a grid, the litter works well.
If you would like to report your findings of foreign objects in YN to the makers of the litter, phone 800-778-1205. To have photos of your findings included in this page, contact Susan.
Note: All of the YN litter I use is cat litter; the customer service rep assured me that the only difference between the cat litter and the rabbit litter is size of pellets, not content.
Bag 1
This photo shows the dangerous objects and, for size comparison, some of the good pellets.

Bag 2
Bag 2 contained numerous short, sharp pieces of metal, some of which appear to be broken staples. An external or internal injury from a piece of metal could lead to an abscess.

Bag 3
Bag 3 included something that looked and felt like a piece of rubber band. It has been circled on the photo.

Bag 4
Some of the litter pellets, such as those near the blue plug, have metallic bits compressed into them.
