Katy recently came out with her InstaGlam Makeup Collection by Covergirl. With several shades of foundation, concealer, lip color, and nail polish, there is bound to be something that suits your skin. Especially when choosing a foundation, pick a shade that makes your skin light and young, just like Katy’s makeup. Katy’s famous eyebrows are strong and full. Whether or not that look is for you, your brows still need to be on point. Using tweezers, gently remove any stray hairs. When you’re content with the shape, use an eyebrow pencil (for beginners) to gently stroke outwards into the shape of your brows. Use short strokes to keep a natural look. This will keep them looking full and soft yet defined.  If you are a novice or expert, try using an angled brush with a powder instead of an eyebrow pencil. This gives you more control and allows you to better shape your brows.  If you’re having trouble seeing your brow shape, try gently brushing your eyebrows directly upwards. This will help bring out their natural shape and allow you to fill them in easier. It’s no secret that Katy has thick and wild eyelashes. To help define your lashes, apply your mascara in small back-and-forth motions across the eye, while spinning the brush up and out. This helps coat your eyelashes evenly. Continue this all the way to the tips of your lashes for added length.  If your lashes are particularly thin, angle the mascara brush upwards and apply your mascara. This helps apply a larger coat of mascara while keeping your lashes from clumping.  Still not enough? Dust baby powder with a brush onto your lashes and then apply mascara. The microscopic flakes of powder will add dimension and thickness to your natural lashes. Katy often wears toned down eye makeup and big eyelashes finished with a bold lip. Experiment with greens, blues, reds, purples, and yellows. If you feel unsure about such bold colors, initially try a soft pink or coral lip. Remember, there are no rules to lip color. Another option is to try a colored gloss or stain instead of a lip stick. Gloss will often be less bold while a stain is great for lasting throughout the entire day.  To maximize lip color, blend concealer onto your lips before applying lipstick. This gives your lipstick boldness and prevents it from bleeding off of your lips.  Another option for staying-power and boldness is dust a layer of translucent powder atop your lips in between application. This keeps the lipstick from sliding around and retains the color.

Article: You should keep your guinea pigs separate from one another in a different room for the first two to three weeks. You will need to have the new guinea checked out by a vet during this time to ensure they are healthy. Do not let them have physical contact until this time period is up.  Placing the new guinea pig directly in the cage with a new one can cause undue stress as they must be eased into a new environment, and their presence may cause the current pig to become territorial. In addition to the emotional concerns, many guinea pig illnesses, which are easily spread at pet and department stores, can incubate for long periods. You need to make sure your new guinea shows no signs of sickness before introducing them to your old guinea.  Put the guinea pigs in separate cages next to each other. Position the cages in such a way that the guinea pigs cannot see each other but can smell and hear one another. Once the two to three week quarantine period has passed, it's time to introduce the guinea pigs. However, do not place the new guinea pig in the cage right away as it's best to introduce them on neutral ground so neither guinea pig feels their territory is being threatened.  Find a new territory where neither guinea pig has been before, but that is a secluded and quiet place where both guinea pigs will feel safe. On the floor of a closed-off and small room, such as a bathroom, is a good option.  Put veggies, treats, and hay in the center of the area to distract the guinea pigs from fighting as they get accustomed to one another's presence.   In case the guinea pigs get physically aggressive, you should have old towels on hand. You can use towels to restrain the guinea pigs while avoiding getting scratched yourself.  If it goes well, and the guinea pigs have not fought for over two hours, you will be able to introduce them to the same cage. Ensure that the cage has been thoroughly cleaned, and all the toys re-arranged to make it seem like a new cage. After the guinea pigs have been introduced, there are steps you can take to smoothen the transition before placing them in the same cage.  Make adjustments to the cage. Guinea pigs are territorial, so make sure your cage has enough space. As a general rule, a cage between 7.5 and 10.5 square feet is recommended for two guinea pigs. More room is preferred, and if you're housing three or more guinea pigs aim for at least 13 square feet. Rearrange and wash the cage so it will smell new and feel more like neutral territory for both guinea pigs.  Gently rub hay from the old cage on the new guinea pig so he smells more like the rest of the herd.
