All animals are checked before despatch but please ensure your order is correct on receipt. The nature of biology, especially of inbred and genetically altered animals, is such that the Animal Resources Centre cannot provide surety against complications or conditions arising after despatch and within the first 24hrs. In the event of abnormalities or losses due to transport, please notify the Animal Resources Centre within 24 hours of delivery. No responsibility will be accepted for late notification. Replacement of stock or credit will be negotiated. All customer concerns will be investigated and are treated as opportunities to improve our business. Concerns about the phenotype or genotype of a strain should also be promptly reported to us.
