Thanks for using Petco Pet Education Center, formerly Petcoach! Lethargy can be caused by a lot of things including an infection, inflammation, among other possibilities. This could also be normal in a kitten as they are not always very active at that age. If you think she is sick it would be best to have her evaluated by a veterinarian for further assessment and treatment. Have a good night!

    Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Puppies can go through phases of being sleepy or having lots of energy. If this persists or Gizmo begins to show other symptoms such as lethargy, vomiting, diarrhea, etc. then I would recommend having a veterinarian examine him so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
