Wild? At common law the domestic cat was never 'ferae naturae', that is seen as 'wild', but 'mansuetae naturae' ,that is 'tame'.The distinction was important because the owner was not liable for the cat's injuring someone unless the owner had prior knowledge of the tendency. (That applied to dogs too, hence the old idea that any dog was 'allowed' a first bite. On a second occasion the owner would be liable, as they'd be on notice of the tendency )
Trespassing? It was held by the Court of Appeal in Buckle v Holmes [1926] 2 K.B. 125 that an owner is not liable for damage occasioned by their cat wandering off.It follows from that that the onus is on others to keep cats out, not on the owner to keep their cat in.
