Hold your cat on your lap in the room where you keep the guinea pig. Have the room to the door closed, and allow the guinea pig to roam around the room outside of its enclosure.  Wait until the guinea pig approaches and assure the cat with affectionate petting if it remains calm. It they can noses one another and remain calm, they are likely ready for supervised playtime. The room with the guinea pig enclosure is best, as the guinea pig can return to its own space if it wants to do so. Always maintain active and vigilant supervision.  Don't ever allow the cat to enter the guinea pig's enclosure. Interrupt your pets' interactions if the cat begins to stalk the guinea pig or either animal begins to get agitated or aggressive.  Try again another day. If aggressive behavior continues, spend time holding the cat in your lap while the guinea pig roams. Make sure they are both in the respective zones where the other is never allowed.  This will allow each to feel most comfortable while you're away, and minimize the risk of coming home to blood-speckled walls. Even if they become great friends, don't ever leave them alone together.

One-sentence summary -- Let your guinea pig roam. Allow the cat and guinea pig to get to know one another. When you aren't in the house, keep the guinea pigs and cats separate.

Q: Your voice in your head sounds different than your voice to other people. To give yourself a good idea of how you sound while doing your impression, record it on your phone and play it back to see how you're progressing. Jim Carrey famously practiced many hours each day in front of the mirror. Use a mirror to see what you look like when doing an impression, and adjust your facial expressions based on whether you are over- or under-doing it. If you’re trying to do an impression of Victoria Beckham, you’ll want to make sure you’re not allowing much emotion in your facial expressions. Practice speaking in her posh British accent in front of the mirror and concentrate on looking bored and annoyed. Coming up with something to say in a given voice can be difficult. To give yourself a wealth of sentences, just read in the voice that you're working on. Vary the tempo and the emotion behind it while you read to practice the different ranges of the voice that you're trying to work out. This will also help you figure out what kinds of words or phrases work well in that voice and what don't. In this way, you can start crafting a better impression. While driving, turn on the radio and repeat back what's being said or sung in the voice that you're working out. This is particularly good for impressions of singers. Doing a Britney Spears song in a Jim Morrison voice will also be humorous to reveal to your friends. Like playing an instrument, a good impression needs to be maintained. Don't let your Shatner get rusty. Even after you think you've got a good impression worked out, go back to it every now and then to keep the impression fresh. Consider adding dimensions to the impression. Will Ferrell's President Bush impression grew in complexity over the many years that he performed it.
A: Record your impression. Practice in the mirror. Read aloud from a book or magazine. Repeat what you hear on the radio. Keep working on it.

Article: Bring out the best in your softer, round features by contrasting them with some edge. Go for sleek lines and tapered ends and avoid bulky hairstyles. Consider a medium-length cut with  layers that frame your face. Have the styles make your shortest layer fall below your ears. Your longest layer should fall a few inches below your chin. Longer cuts look great with round faces because they tend to lengthen the features that are typically shortened. You can grow your hair out if it is already long, or if it is already long, ask for it to be cut into layers. For example, consider long wavy layers because they contrast round features. Asymmetrical styles can be a bold, beautiful move for people with round faces. Long, layered bangs create edgy angles that offset round features. An angled bob is another great choice for people who want a shorter cut. A pixie cut will put the focus on your features rather than your hair. This type of cut will bring out your apple cheeks as well as your eyes. Plus, a pixie cut is fairly low maintenance when it comes to styling.

Create angles to frame a round face. Get long, wavy layers to lengthen and contrast your features. Experiment with an asymmetrical style for a bold cut. Choose a pixie cut to bring out your features.

Article: The figure eight knot has a firm, non-slip loop at the end. It is one of the strongest knots there is and ideal for mooring boats. Measure 24 inches (61 cm) from the end of the rope, then wrap the rope into a loop. The tail needs to cross in front of the rest of the rope. Hold the loop in your non-dominant hand. Use your other hand to wrap the tail end of the rope behind the rest of the rope, just under the loop. Pull the tail end upwards and push it through the loop. Pull upwards on the tail end and downwards on the rest of the rope to tighten the knot. If you have enough rope leftover, you can use it to retrace your knot. Simply weave the tail around the knot, following the rope that's already there. This will make the knot larger. If you want to, you can leave a loop at the bottom to hook onto things.
Question: What is a summary of what this article is about?
Use a figure eight knot if you need something strong. Make a loop near the end of the rope. Wrap the tail end behind the rest of the rope. Feed the tail end through the loop, then tighten. Use the end of the rope to retrace the knot, if desired.
