One type of cat feeder is a type that refills from a reservoir as your cat drinks from the bowl. These can be used to feed one cat for several days even. You can use these to feed multiple cats too. There are some disadvantages to using them though. For example an aggressive cat can easily prevent the other shyer cats from getting enough food. Although your cat is not likely to be pouncing on their dinner anymore, they still instinctively need to sharpen their claws and that is exactly what they are doing on your furniture. The scratching that they do is a way of trimming their nails and it removes the old outer part of the claws. Another reason they are ruining your home is because they know it to be their territory.

Cats really should derive the majority of their nutritional needs from protein, so cat foods that are high in carbohydrates may not necessarily be the best for them. Interestingly enough, many of the premium brands of cat food offer exactly what most cats need, and aren t necessarily more expensive in the long run. If you are concerned about your cat going missing, or it being involved in an accident, you can have a micro-chip (approximately the size of a grain of rice) inserted into the back of the cat s neck. The chip contains information, which can help to identify the cat as belonging to you. It is often said that a cat looks after itself . It will depend on you throughout its life around 15 years with proper care so properly budget for visits to the vets and other costs before making a decision to get a cat. You have to budget for cat food, cat litter and scoops and other accessories to make the cat s life comfortable at your home. Kitten or adult?

Clicker training is associated with classical condition (they associate the sound with food.) and operant conditioning (cat performs movement to receive food). Why use a clicker and not tell a cat or make a sound to get your cat to do a trick?
