Pets make waste; it's a fact of life. We (the humans) must deal with their waste. I came up with this idea when getting two baby guinea pigs; I had wanted a small furry creature for about a year. Sometimes when you hold them, you hold them for a "little" too long and they have to "go". Within a few minutes you find yourself changing into a new shirt. My first solution was to hold them in a blanket. That holds the feces, but you still find that you're holding a wet towel. This "Pet-Proof Pet Liner" is a blanket combined with a waterproof mattress protector.
Step 1: Materials
For this instructable you will need....
1. A Blanket (I use fleece, the animals like it)
2. A Waterproof Mattress Protector
3. Means of Sewing and Thread
Blanket + Waterproof Mattress Protector = Happy, Dry Human
Step 2: Prepare the Mattress Protector
The entire mattress protector has the part which goes on the bed and the part which wraps around the bed. Cut the "wrap-part" from the "bed-part". Keep the "bed-part", do whatever you want with the "wrap-part"
NOTE: I didn't get the chance to take pictures of this step and I didn't want to dissect another mattress protector. All you have to do is cut the two parts; you shouldn't have much trouble without the picture.
Step 3: Cut
Cut the blanket and the mattress protector to the desired size. If you don't use the entire protector (and you probably won't), you might want to consider sewing the cut edge to keep it from coming undone.
Step 4: Sew
Sew the blanket to the waterproof liner. Remember, whatever sides you want on the outside when the project is finished, must be on the inside when sewing. Sew most of the way leaving a small gap. Turn the blanket right-side-out. Finish sewing.
Step 5: Further Uses
That's it you're done. After a while I figured out this liner could be used for other things too....
You could place inside pet-carriers for stressed pets. You could use this as bedding in a "potty-trained" animal's cage, referring to small animals with litter boxes (Guinea Pigs, Hamsters, Gerbils, etc...). They must be trained because this blanket can't absorb great amounts of waste, instead it is meant to help with the occasional "accident". The possibilities are endless....
NOTE: When holding animals with the modified blanket, it works best to hold them so they're touching the blanket, and your hands are on the mattress protector.
