Fearful cats also express other problematic behavior: Socialization important already at early stages of life

“We wanted to find out what factors are associated with the problematic behaviour of cats, such as fearfulness, aggression towards humans and excessive grooming. We utilised a survey dataset previously collected in our research, which we have already used to investigate the construction of the feline personality,” says Doctoral Researcher Salla Mikkola from the University of Helsinki and the Folkhälsan Research Center

Socialisation important for kittens

The survey included more than 120 statements used to score feline traits.

The fearfulness factor included statements on the cat’s reaction to strangers, sudden noises and changes taking place at home. Aggression towards humans included scratching or attempts to bite in conjunction with care, such as when being brushed. Excessive grooming included extensive and intensive grooming as well as self-mutilation by pulling hairs off with teeth, or by biting or licking.

“We investigated the link between these problematic behavioural and personality traits, and almost 30 behavioural, environmental and biological factors. For example, the socialisation of cats with humans was associated with fearfulness. Cats who had come into contact with unfamiliar adults and children under 12 weeks of age only a few times or not at all were more fearful than cats who met strangers on a weekly or daily basis. Fearful cats also received, on average, higher scores for litterbox issues, aggression and excessive grooming,” Mikkola says.

Prior studies have also shown that fearfulness can lead to aggressive behaviour, such as hissing and biting, if the cat sees no other way out of a frightening situation. No direct causalities can be established on the basis of the data.

“There were less aggression and fearfulness in households with more than one cat, but we cannot say for certain why this is. It may be that the companionship of other cats is an important stimulus for cats, or alternatively, people don’t want to take a mate for their aggressive cat due to its nature. Research carried out through a different design is needed to explain causalities,” says Professor Hannes Lohi.

Next, Professor Lohi’s group will conduct research on feline litterbox issues.
