AB  - The advent of globalisation and urbanisation has caused city populations to grow larger and
faster by the day. As these populations grow so do the populations of domestic cats. Problems related
to free-roaming stray cats are becoming increasingly important due to factors such as animal-welfare public
health issues and various societal impacts. Though, it may be true that there are many means to resolve this
problem it is crucial that this problem be resolved in the most sustainable, cost-effective and humane way
possible. This study posits that the current methods to control the stray cat population are ineffective and
hence proposes a more innovative and humane design in order to trap stray cats. The TRIZ methodology was
used in this study. The common cat trap design was studied using function analysis and cause-and-effect chain
analysis. A few engineering contradictions were formulated. An innovative way to capture cats was proposed
by resolving these contradictions using a few selected inventive principles namely segmentation, asymmetry,
beforehand cushioning, equipotentiality and dynamisation. This innovative cat trap was also proven to be
feasible and affordable with an estimated cost of MYR 80. The cat trap is expected to catch a maximum of 4 cats.
Overall, the proposed trap is sustainable, cost-effective and humane and indeed addresses the issue as an
effective method in controlling the stray cat population.
