Cat Climbs Mountains And Desert Treks

Other common household substances that should be used with caution around cats include mothballs and other naphthalene products. Phenol-based products (Pine-Sol, Dettol (Lysol) or hexachlorophene) are often used for cleaning and disinfecting near cats' feeding areas or litter boxes but these can sometimes be fatal. Ethylene glycol, often used as an automotive antifreeze, is particularly appealing to cats, and as little as a teaspoonful can be fatal. Some human foods are toxic to cats; for example theobromine in chocolate can cause theobromine poisoning, although few cats will eat chocolate. Large amounts of onions or garlic are also poisonous to cats. Many houseplants are also dangerous, such as Philodendron species and the leaves of the Easter Lily, which can cause permanent and life-threatening kidney damage.
Behavior
Free-ranging cats are active both day and night, although they tend to be slightly more active at night. The timing of cats' activity is quite flexible and varied, which means that house cats may be more active in the morning and evening (crepuscular behavior), as a response to greater human activity at these times. House cats have territories that vary considerably in size, in one study ranging from seven to 28 hectares (69 acres). Although they spend the majority of their time in the vicinity of their home, they can range many hundreds of meters from this central point.
