Sea otters rescued from oil spills, entanglement, and stranding face intensive rehabilitation with complex welfare considerations, and successful release requires careful assessment of survival capability.
Sea otter rehabilitation involves acute welfare trade-offs. The decontamination process itself — extended handling, warm water baths, and forced feeding — is profoundly stressful for an animal that naturally avoids close human contact. Repeated handling during recovery, blood sampling, and medical treatment compound stress. However, the alternative for an oiled otter is hypothermia and death — the welfare calculus strongly favours intervention. Long-term welfare of non-releasable otters in aquaria requires enrichment, social housing where possible, and complex aquatic environments. The surrogate program, where non-releasable female otters foster wild-born pups, represents an elegant solution that benefits both resident and releasable animals.
