  • Patent number: 11641842
    Abstract: The present disclosure provides methods for enabling an individual having a cat allergy to have a cat as a pet. Such a method can include quantitatively determining a threshold in the individual for an environmental level of an allergen produced by the cat and selecting a cat or a breed of cat that creates an environmental level of the allergen that is less than the threshold. Additionally, such a method can include lowering the allergens disseminated by the cat by treating the environment inhabited by the cat during a time period where the cat expresses elevated allergens.
    Type: Grant
    Filed: June 9, 2021
    Date of Patent: May 9, 2023
    Assignee: SOCIÉTÉ DES PRODUITS NESTLÉ S.A.
    Inventors: Ebenezer Satyaraj, Peichuan Sun, Scott Sherrill, Qinghong Li, Steven Hannah

  • Patent number: 10889785
    Abstract: Formulations, compositions and products for reducing allergenic Fel d 1 from the environment are disclosed. The formulations include at least one protease that interacts with the Fel d 1 and substantially degrades allergenic epitopes on the Fel d 1. Methods of using the formulations for reducing or eliminating allergenic Fel d 1 from the environment are also disclosed.

  • Patent number: 9322832
    Abstract: The invention provides methods for diagnosing degenerative joint disease in an animal by collecting a saliva sample from an animal; determining the amount of at least one diagnostic agent selected from the group consisting of interferon gamma, interferoninducible protein-10, interleukin-2, and total saliva protein in the saliva sample; comparing the amount of diagnostic agent found in the saliva sample to a corresponding amount of the same diagnostic agent found in a saliva sample from one or more comparable control animals that do not suffer from degenerative joint disease; and diagnosing that the animal is susceptible to or suffering from degenerative joint disease if the amount of diagnostic agent in the saliva sample from the animal is greater than the amount of same diagnostic agent found in the saliva sample from the one or more comparable control animals.

  • Publication number: 20140134747
    Abstract: The invention provides methods for determining if an animal's metabolism has been shifted to ketogenic status by collecting a first urine sample from the animal when the animal's metabolism is not in a ketogenic status; collecting a second urine sample from the animal when the animal's metabolism is possibly in a ketogenic status; analyzing the first urine sample and the second urine sample for beta-hydroxy butyrate; and determining that the animal's metabolism has been shifted to ketogenic status if the concentration of beta-hydroxy butyrate in the second urine sample exceeds the concentration of beta-hydroxy butyrate in the first urine sample by ten percent (10%) or more.
