چکیده
Ž The present study is aimed at finding taste reactivity patterns in domestic cats Felis silÕestris . catus which reflect ‘liking’ or perceived palatability. Three groups of nonstressed cats living in households were formed which a priori were expected to differ in motivational state for eating Ž . food items more or less hungry , and which were offered two different food items differing in Ž . general taste properties more or less flavourful food, MFF and LFF, respectively around the time that they were fed their normal food. Analysis of the amount of food eaten showed that MFF was consumed regardless of hunger level and that LFF was consumed depending on the hunger level of cats: the more hungry cats ate more of LFF than the less hungry cats. Analysis of post-meal behavioural sequences showed that the ‘MFF consumption sequence’ differed from the ‘LFF refusal sequence’ and that the ‘LFF consumption sequence’ strongly resembled the ‘MFF consumption sequence’ but also contained elements of the ‘LFF refusal sequence’. Subsequent analysis of the frequencies and total durations of behavioural patterns showed that two kinds of patterns existed, possibly reflecting two ‘palatability dimensions’: hedonic taste reactivity patterns Ž . Ž lickrsniff feeding bowl, lip lick and groom face and aversive taste reactivity patterns lickrsniff . food and lick nose . These dimensions may be combined to obtain a single palatability score. q 2000 Elsevier Science B.V. All rights reserved.

First Complete Genome Sequence of Felis catus Gammaherpesvirus 1
We sequenced the complete genome of Felis catus gammaherpesvirus 1 (FcaGHV1) from lymph node DNA of an infected cat. The genome includes a 121,556-nucleotide unique region with 87 predicted open reading frames (61 gammaherpesvirus conserved and 26 unique) flanked by multiple copies of a 966-nucleotide terminal repeat.

How cats lap: water uptake by Felis catus.
Animals have developed a range of drinking strategies depending on physiological and environmental constraints. Vertebrates with incomplete cheeks use their tongue to drink; the most common example is the lapping of cats and dogs. We show that the domestic cat (Felis catus) laps by a subtle mechanism based on water adhesion to the dorsal side of the tongue. A combined experimental and theoretic...

The home ranges of four male and five female feral house cats (Felis catus) were studied by radiotelemetry. In the narrow, steep-sided valley the home ranges of cats were linear, with an average length of 6.34 km for males and 3.83 km for females; only large males crossed the river. Females with kittens had small home ranges of 0.84 to 2.0 km. Home ranges of animals of the same sex, including b...
