Domestic cats (Felis catus) do not show causal understanding in a string-pulling task

Area of Science:

• Animal Cognition
• Comparative Psychology
• Ethology

Background:

• Understanding physical causality is a key cognitive ability observed in many species.
• Investigating causal reasoning in domestic cats (Felis catus) can provide insights into their cognitive capacities.
• Previous research has explored various aspects of cat cognition, but causal understanding remains less understood.

Purpose of the Study:

• To investigate whether domestic cats understand physical causality through a string-pulling task.
• To determine if cats can associate a string with a reward and understand its function in retrieving a treat.
• To assess cats' ability to discriminate between relevant and irrelevant strings in different configurations.

Main Methods:

• Fifteen domestic cats were presented with a horizontal string-pulling task.
• Three setups were used: a single baited string, two parallel strings (one baited), and two crossed strings (one baited).
• Performance was measured by the cats' ability to consistently select the correct string to retrieve an unreachable food treat.

Main Results:

• All cats successfully retrieved the treat using a single baited string.
• When presented with two parallel strings, no cat consistently chose the correctly baited string.
• With two crossed strings, only one cat consistently chose the incorrect string, while the rest performed at chance level.

Conclusions:

• Domestic cats demonstrated an inability to consistently understand the physical causality involved in the string-pulling task.
• Cats did not show evidence of understanding the functional relationship between the strings and the food reward in more complex scenarios.
• The study suggests limitations in cats' causal reasoning abilities concerning tool-use-like tasks.
