My 6-week-old kitten has a low pulse and sleeps all the time.

It sounds like Jenny is pretty sick. Viral infections are very common in kittens and can make them sick very fast. The high heart rate worries me that her body is struggling to maintain normal blood flow or normal oxygen levels in her blood stream. I recommend to take her into the veterinarians office asap as this sounds like an emergency. The doctor will provide supportive care (fluids, antibiotics) and may recommend a radiograph to rule out pneumonia. Take Jenny needs care fast. Best of luck.

This is very concerning. Your kitten sounds very sick. I think she may have a virus (or possibly a large parasite burden). You should take her to the emergency vet as soon as possible to see what can be done. Before you leave, apply a little honey or syrup around her mouth as she may be weak from having a low blood glucose level. I hope she pulls through.

That is not normal behavior from a young kitten. Yes it sounds like she has a fever and stomach upset. Since she’s so small and sick she should have veterinary treatment soon so she doesn’t get worse. Healthy kittens are very playful and don’t vomit or sleep that much. Please take her in for treatment. They will give medication to resolve the vomiting and reduce her fever if she has one. She may need fluids to prevent dehydration and she may need to be dewormed also. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for your kitten.

I would have her looked at by a veterinarian. My concern if she is just laying around, has seen eaten? If not then her glucose can be dropping. She may be dehydrated. It is something where a veterinarian needs to evaluate her. Thank you for using Petco Pet Education Center, formerly Petcoach.

Kittens can sleep a lot, but if she is very listless I would be worried that she is ill and should be seen by a veterinarian right away. Starvation and dehydration can very quickly cause a kitten to go downhill which could be why she is so lethargic and requires medical care. She may also be younger than you suspect and still need additional care. Your vet can also help determine her age, and you can use this guide if she is young for rearing orphaned kittens: https://www.petcoach.co/article/how-to-raise-orphan-kittens/

Thanks for using Petco Pet Education Center, formerly Petcoach! This is considered very abnormal in a cat. Abnormal breathing in a cat can occur from conditions such as pneumonia, heart failure, asthma, bronchitis, among other possibilities. If her pulse (not respiratory rate) really is 70 bpm as you pointed out that is very abnormal for a cat and at the same time even if it was her respiratory rate it would also be abnormal. For that reason, I highly recommend that you have Marciella evaluated by your local emergency clinic or your veterinarian if open as soon as possible for further assessment and treatment. Likely diagnostics include chest radiographs. Treatment would be dependent on findings. Good luck!

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!
