20. The owner of a cat or dog must take reasonable steps —
(a)
to ensure that the cat or dog (as the case may be) is kept in a safe environment that minimises the risk of death or serious injury to the cat or dog (as the case may be);
(b)
to prevent the cat or dog (as the case may be) from being in any place which exposes the cat or dog (as the case may be) to the risk of falling from height (whether from within the premises where it is kept by the owner or elsewhere); and
(c)
to prevent the cat or dog (as the case may be) from leaving the premises where it is kept by the owner, except under the physical control of the owner or any individual permitted by the owner to have control of the cat or dog, as the case may be.
