In a study in 1996 by Bernstein and Strack, some interesting observations were made regarding the interactions and movements of unrelated domestic cats in a multi-cat household. 14 cats were observed. The cats were all “non-reproductive” (presumed altered). Their ages ranged from 6 months to 13 years. The home was in America and it was a single-storey home with 7 rooms, several closets and 2 bathrooms. The cats were observed for at least 4 hours a day, 7 days a week over the period from late January to April 1981. The total time the cats were observed was 336 hours. Most of the observations were made just before and after morning or evening feeding. The cats’ caretakers were present during the study and were allowed to interact freely with the cat.
The study focused on what the cat’s themselves did in the home and what rooms they used including their favourite spots and which other cats they spent time with. The patterns of behaviour changed over time and with the composition of the cat groups.
Individual cats in general had places where they could normally be found at certain times of the day. The death of a dominant cat affected the spacing of the cats and their behaviour but these cats were very rarely seen to interact with the dominant cat when he/she was alive.
Female cats remained in fewer rooms than male cats whereas male cats were more likely to roam between the various rooms. The kittens used more rooms than the older cats. As the kittens became older they used less rooms. Each individual cat had specific rooms that he/she used on a regular basis. Each cat, on average, used 5 of the 10 available spaces.
Of the favoured spaces within the home these were more likely to be time-shared between the cats rather than physically shared. What this means is that an individual cat would use the space and then leave it whereupon another individual cat would enter the space. This is timesharing as opposed to both individual cats sharing the space at the same time. Most time-sharing of spaces occurred amongst same-sex pairs i.e. female/female or male/male.
“Within gender, specific individuals timeshare specific spots.”
Within the study only one adult male/adult female time-shared. This means that timesharing is most often between same-sex individuals.
The cats appeared to have established relationships and they knew their places whilst there was very little overt aggression. Certain individual cats were dominant. The dominant cat controlled who went where and who avoided whom. They also controlled who conceded space to whom and who took over places which had been vacated. This was a very simple hierarchy of the dominant cat and the rest. There appeared to be no hierarchy below the dominant cat.
Conclusion? The social structure appears to be well ordered in order to create harmony – the modern domestic cat is sociable and organised in groups. Despite that in my experience of reading comments on PoC there are situations where individual cats do not get along and time and patience might not resolve the problem or partially resolve it.
