Housing for an Asian small-clawed otter is not for everyone. The otter does have a natural odor that you may want to consider when placing their caging. All otters are able to climb wire fencing, bushes and trees so a roof is recommended or a solid wall barrier. Also there needs to be a solid flooring or wire dug down to about 3 feet below the walls to stop from the otter digging out. They need an area to be able to exercise, forage and digging. A clean water source to be able to swim in daily. This species of otter is found in tropical climate so does not do well in cold climates. They need to be at 50 degrees Fahrenheit, if temperature goes below, you will need to provide a heated indoor area for them to go into. The water temperature needs to be about 75 degree Fahrenheit. Dry bedding or area with dry flooring needs to be available at all times. If the otter does not have an area to dry off and does stay wet for extended periods, it will lead to health issues. Asian small-clawed otters are not compatible to be housed with other species of otters.
A separate water bowl, which is small enough that the otter cannot swim in, needs to be provided for clean drinking water.
The diet of an Asian small-clawed otter in captivity consist of canned or dry cat food, that is designed to control calcium oxalate uroliths, fish, crickets and mealworms. Supplemental vitamin E and thiamin needs to be also included in their diet.
Vaccines recommend are for leptospirosis, rabies, parvovirus and canine distemper. Otters can get heartworm disease and should be administered ivermectin as a preventive.
