How to Cut Guinea Pig Claws
To cut your guinea pig's claws, start by getting baby or animal nail clippers and some styptic powder or cornstarch in case its claws start bleeding. Then, when you're ready to get started, loosely wrap your guinea pig in a hand towel, and position it in your lap so it's facing away from you. Next, gently grab one of your guinea pig's legs, and carefully trim its claws with the clippers, making sure you don't cut into the pink quick. When you're finished, repeat with the rest of its legs.
Select a pair of nail clippers. Baby or animal nail clippers will work, so you could use either type. Keep in mind, however, that human clippers squeeze the nail together before clipping it; this may be painful to your guinea pig. Animal clippers are guillotine-style, ensuring that the nail won't be squeezed. Also, they open more widely than human clippers, which makes the nails easier to trim. You can find this type of clipper at your local pet store. You can try both types of clippers to see what your guinea pig is most comfortable with. Make sure to be careful of the quick. The quick is the reddish part at the base of the toenail. Try not to cut into it, as this will cause your guinea pig to bleed. If you can't see the quick, try holding a flashlight up to the nail when you cut it or only cut the tip-off. Purchase styptic powder or corn starch, if you do not have them already. These substances will quickly stop the bleeding if you trim the nails down too far. They are equally effective at stopping the bleeding, so you can use either one.  Styptic powder can usually be found with men's shaving products at your local grocery store or pharmacy. Cornstarch is located with the baking products. Select a hand towel. In case your guinea pig is squiggly during nail trims, you can wrap him/her up in the towel to restrain him/her more easily. If you have previously used a towel to trim his/her nails, keep using the same towel each time. This will help to keep the process more consistent. Plus, he/she may feel more comfortable with one towel over another. Prepare the area where you will trim your guinea pig's nails. Organizing everything that will you need for the nail trimming ahead of time will help the process go more smoothly. Place a small towel, nail clippers, and styptic powder (or cornstarch) on a counter or tabletop. Placing a small amount (about 1/4 teaspoon) of styptic powder or cornstarch on a paper towel ensure that you have quick access to these substances if you need to stop a nail from bleeding. Take your guinea pig out of his/her cage. After reaching into the cage with a slow and steady movement, place the thumb of one hand under his/her jaw and support his/her hindquarters with your other hand. Using the proper method to reach into the cage and pick up your guinea pig will not only ensure that he/she is not frightened but will also keep you from getting bitten. Wrap your guinea pig in the hand towel. Be careful not to wrap your guinea pig too tightly; this could cause him to quickly suffocate or overheat. Position your guinea pig in your lap. He/she should be facing away from you, which will make it harder for him/her to bite or nip. Relax your guinea pig. There are several things that you can do to relax your guinea pig before trimming his nails, such as petting him/her gently behind his/her ears and giving him snacks. Make sure you don't have any food around him/her so he/she doesn't get tempted while getting his/her nails trimmed. Keeping him/her relaxed will help you trim his/her nails more easily. Healthy snacks for your guinea pig include bell peppers and carrots. Cut the vegetables into small pieces so that your guinea pig can eat them easily. Choose a leg and gently pull it out. Do not be surprised if your guinea pig wiggles when you do this. If he/she wiggles too much, release his/her leg and let him/her calm down before you try again. Secure one of his/her nails. Using the hand that is holding your guinea pig's legs, steady the nail between the thumb and index finger. Do not squeeze too tightly to keep the nail in place; this may hurt your guinea pig and cause him/her to squirm. Selecting a nail on one end of the foot and working your way to the inside or outside of the foot will help you keep easier track of which nails you've trimmed. Pick up the nail clippers with your other hand. Position them in front of the nail that you are about to trim. Identify the quick in the nail. Identifying it will be easier to do with a clear nail than a darker nail. In clear nails, the quick will look pink. Trim the nail. If you can see the quick, trim the nail down to just above the quick. If you cannot see the quick, use caution and trim a little bit at a time. If you cut the quick, the nail will start to bleed. Although this will be painful to your guinea pig, you have not caused any serious damage. Simply dab a small amount of the styptic powder or cornstarch on the nail and the bleeding will stop quickly. Proceed with trimming the rest of your guinea pig's nails. If you see that your guinea pig is becoming restless, give him/her some time to calm down before trying to finish trimming his/her nails. Giving your guinea pig a treat after trimming each nail can provide positive reinforcement and keep him/her distracted. Make sure that he/she finishes eating before starting on the next nail to prevent him/her from choking on his/her food. Put your guinea pig back in his/her cage and tidy up the nail trimmings. If this was your first time trimming your guinea pig's nails, don't be too hard on yourself if things didn't go quite as expected. Guinea pigs will wiggle when getting their nails trimmed at any age. If this time didn't go well, consider trimming your guinea pig's nails over several days instead of all at once. This may be easier for both of you. If you put styptic powder or cornstarch on any of the nails, check these nails to make sure that the bleeding has stopped. Wipe off the substance from the nail before you put your guinea pig back in his cage to prevent him from eating it on accident.
