The cleverly engineered touch sensitivity system distinguishes between "touch" and "grip". When you tap it, your hand needs to be removed from the faucet within a fraction of a second. If the hand stays on the faucet, it is identified as a "grip", and the faucet does not respond. So it is practically impossible for pets to activate it.
But there are faucets on which the spots will be much less visible and easier to clean. You only have to find a faucet with a surface designed especially for the clean look. If you do an online research, you can find references to such a feature in the descriptions that are available on the manufacturers′ or retailers′ sites. If you find a site that does not offer you a detailed description, it is a good reason for you to leave that site. There are a lot of customer oriented sites on the Internet that supply even more information about the items they feature than you can possibly get at your offline store.
Second - Disassemble the Faucet: The same basic principals apply to all faucet types when starting to take a faucet apart for repair or replacement. Keep all parts and layout in the order you take them apart. This will help you both put the faucet back together and identify the parts to be replaced. See below for specific variations in faucet dis-assembly.
Ball-style Faucet - this washerless faucet has a single handle and is identified by the hollow metal or plastic ball inside the faucet body which controls water temperature and flow. Many have a rounded cap with knurled edges located under the faucet handle. Dripping at the faucet spout is caused by worn valve seats, springs, or a damaged ball. Leaks around the base of the faucet are caused by worn o-rings.
