One of the most common signs of ear mite infection is the scratching of the affected ear. This ear scratching is because ear mites can cause considerable irritation. The rabbit may scratch his ears with his paw or rub his ears on the ground. Your rabbit may also shake his head or hold his ear over to one side. Your rabbit's ears may have reddened or inflamed skin. Irritation from the feces and saliva of the mite causes extreme itchiness, and the rabbit scratches and traumatizes the ear. A severe infection due to ear mites is characterized by distinctive yellow-gray debris and scale that builds up and fills the ear canal. This debris and discharge is tightly adhered to the skin. Attempting to remove the debris causes pain. Forcible removal tends to peel away the top layer of skin with the discharge leaving a large ulcer behind. Typically in the early stages of infection, close inspection may show scales of skin tightly stuck to the ear canal. If ear mites are left untreated, the weight of the collected debris inside the ear can cause it to drop. The rabbit may develop secondary bacterial infections where the skin is damaged, and infection may spread inwards into the middle and inner ear causing poor balance and a head tilt.

You'll need at least three people to play, but this game can involve many players. With a large enough space and enough hiding spots, you could play with well over 20 players. Get together a group of kids from your neighborhood, from school, or from after school clubs to play this game with you. Invite kids your age you see playing alone to come play Kick the Can. Say something like, "Hey, we're going to play a group game called Kick the Can. Would you like to play?" Bottles and cans are the typical choice for this game, but you can use anything that could be safely kicked some distance. Other options include balls, small trash cans, small boxes, plastic cones, a plastic bucket, and so on. Give your item a few trial kicks. You don't want it to go too far or too short. Choose an object that can be kicked a medium distance. You may want to put some rocks into your item. Doing this to items like cans, bottles, and boxes can help you adjust the distance an object is kicked. The best play ares will be large, with plenty of hiding places. Playgrounds and parks work great, as do cul-de-sac streets (which are closed off at one end). Clearly agree on the boundaries of your play area with all players. Natural features, like tree-lines, large rocks, and paths are a great way of clearly outlining the boundaries of your play area. If one of your boundaries is unclear, use other items, like branches, rocks, hats, cones, and so on to mark it. The jail is where players go when they're caught by the seeker. Your jail, much like your playing area, should have clearly defined boundaries. Some common places used for the jail include decks, patios, benches, porches, and so on. If you don't have a clearly defined jail in your play area, make one by arranging branches, stones, cones, and more to form its boundaries. The jail should be large enough to fit as many players are playing, but not much larger than that. Use rock, paper, scissors to select the seeker or use whatever method you prefer. No matter how many players there are, there is only one seeker per game. After that, agree with other players on the time the seeker will count before searching for hiders. The more time you have to hide, the more likely it is hiders will have a better hiding place. Use longer count times for the seeker for longer, more challenging games. Short count times can add an fast paced aspect to this game. If you and your friends like quick games, choose short count times. Alternatively, set up the item you're using in place of the can. Arrange this item in a central location in your playing area. This location should be wide open and difficult to sneak up on. You may want to locate your can close to your jail. This way, if the can is kicked, the seeker will have to run towards the jail while jailed players are running away.

Research speakers and see when to use different types. Find out which cords plug into mics and which ones go between soundboards and amps. You need to know how to set up all kinds of sound equipment. You can learn these things online through tutorial videos and also in person when you can work with sound people. Some sound equipment is the same as it was years ago, but many other technologies are continuing to evolve. Staying current on your knowledge is vital. You need to know how mix and edit in music software like Pro Tools and Cubase. If you can, purchase one of these programs and begin exploring what they can do and practice editing songs. Pick a song you like and import it into the software. Practice splitting the song into parts and changing pitches and volumes. Not all sound engineers mix new music tracks, but being able to do it will make you more versatile. It will take time to learn all of the things you can do, but it's important to start building a foundation. Because sound engineers work with so many types of electrical equipment, you will need to learn some basic electrical safety. Learn about basic electricity, such as the difference between voltage and current. You will need to know how many pieces of equipment can be plugged into a specific power strip so you don't blow a fuse or ruin the equipment. Taking classes in physics, for example, is a good place to start. If classes are not an option, consider an electrical safety training seminar. If you are still in school, you have access to some opportunities that others don't. Try to get involved with the theater program, which most likely uses a sound system during plays. Productions are often mostly run by students anyway, so this is an easy way to get hands on experience in a low key setting. In college, you also have some opportunities to get involved in running sound, even if you aren't studying it. Check in with your campus theater and see what they require for their sound people. Find out if you could start working with someone who already does it and learn from them. While you can learn on the job and get lots of experience, earning a degree shows your commitment to learning. It shows that you can work hard on something until it is complete. A degree also shows that you have been properly trained in the field. While it may not be mandatory for some jobs, it's going to make you look better to those looking to hire quality engineers. A typical degree might be an Associate's or Bachelor's of Science in Audio Engineering. The degree might also be called Sound Engineering. These degrees will tend to be a mix of music, business, and technical classes which serve to give you a well-rounded education in the field.
