A clicker is a small plastic box that contains a strip of stiff metal. When pressed, the metal makes a distinctive "click-clack" noise. Clickers can be obtained in most pet stores.  The theory behind clicker training is that the cat will learn to link a sound (click-clack) with a reward (tasty treat). The nice thing about a clicker is that it is a distinct sound which is only associated with a reward. Thus, the cat is much more likely to respond.  Although you can train a cat using just words, it can be more difficult. Because you use words in everyday speech not directed at your cat, the cat probably won't pay a lot of attention to them. Furthermore, if you use a command word such as "shake," the cat will likely hear the word in other contexts and not know when it is expected to respond. Cats can be picky eaters, and a treat that one cat enjoys may be of little interest to another. Training will go faster and more easily if you determine in advance what kinds of treats your cat enjoys most. You may want to try buying a small amount of several different cat treats to try them out and see what your cat likes best. The ideal time for a clicker session is when the cat is relaxed but not asleep, and sitting near you. You can start any time when the cat is paying attention. If your cat has just woken up, it may be groggy. If this is the case, give the cat five minutes or so before you begin training. Once the cat looks alert, press the clicker and give it a treat. Repeat this several times over a period of about five minutes. Cats only  have a short attention span, so don't try to continue your clicker session beyond about five minutes. Later in the day, or the next day, do another clicker session. Continue repeating these sessions regularly until your cat associates the sound of the clicker with a treat.  Each cat learns at a different pace, but most will figure out the link between the clicker and the treat after two or three five-minute sessions. Be consistent, repeating the clicker session once or twice a day, every day, until the cat makes the association.  You will be able to recognize when your cat has discovered the connection, because it will gaze at you expectantly and perhaps lick its lips after your press the clicker.

Summary: Obtain a clicker. Find a treat your cat enjoys. Pick a training time. Train with the clicker. Repeat the session.


Tap the Snapchat app icon, which resembles a white ghost on a yellow background. The Snapchat camera will open if you're logged in. If you aren't logged in, tap LOG IN, enter your username (or email address, or phone number) and password, and tap LOG IN. Swipe right over the Camera page to do so. You should see a list of recently snapped friends appear. Scroll down until you find the name of the person to whom you recently sent a snap. You should see an outline of a triangle and the word "Opened" below the person's name, along the time which they opened the snap listed in seconds, minutes, or hours.  If your friend opened the snap within the last minute or so, they're most likely still online. If you instead see a solid triangle with the word "Delivered" next to it, they haven't yet opened your snap.
Summary: Open Snapchat . Scroll over to the Friends page. Find your friend's name. Look at the "Opened" timestamp for the last snap you sent to them.
