Why are my 8-week-old kittens' throats red? Virus or bacteria?

Hello, poor Freyja. She may be having a recurrent upper respiratory infection. Most common URI are by viruses (herpes and calicivirus) and then there's chlamydia which is bacterial. In addition to the antibiotics she may need to have antivirals such as oral lysine. I would have her rechecked by your veterinarian to rule out the possibility of a recurrent infection. Hope this helps and best of luck!

This may be a virus and not a bacterial infection. If that's the case antibiotics will not help and the virus needs to run its course which can take up to two weeks. As long as she isn't getting worse, running a fever and is eating I would keep monitoring her. If at any time she does get worse or isn't getting any better after 7-10 days, I would call your veterinarian. Let her rest unless she wants to play. Thank you for using Petco Pet Education Center, formerly Petcoach.

Usually these signs are due to a respiratory tract infection/inflammation due to a viral infection. Herpes virus is usually involved. Immediate veterinary intervention is needed as antibiotics may be necessary. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Hi there and thank you for using pet coach to address your concern. In regards to the test results, I would contact your vet to find out what the results were. For the cats you havestarted on doxycycline, the respiratory symptoms may not be due to a bacterial infection but rather a viral infection, in which case, an antibiotic won't treat if it is purely a viral infection. Sure it will treat secondary bacterial infections that may be going on as a result of the primary viral but I wouldn't rely on an antibiotic solely to treat this. I recommend using lysine supplementation. Many times in kittens, they pick up the herpes virus from the mother. Lysine works by lessening the severity and possibly shortening the duration of a herpes viral infection. Duralactin with Lysine is the supplement I recommend to help treat the infection which can be found online. If the infection worsens, a nebulizer may help and sometimes antibiotics are nebulized in severe cases. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Based on your description and the pictures, I suspect that he has an upper respiratory infection. Many times upper respiratory infections can be contributed to the herpes virus in cats. I would recommend taking Catty in to be seen by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. An antibiotic will likely be prescribed / administered to help with any secondary bacterial infections. I hope this helps guide you in the right direction and that Catty feels better soon. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach! I would recommend making sure he does not have an underlying disease that may be predisposing him to these infections. Test him for feline leukemia (FeLV) and feline immunodeficiency virus (FIV) at your veterinarian's clinic to rule these possible causes out. Some cats will have chronic viral infections their entire life and we just treat these as they come. If you are not giving lysine supplementation and not giving Purine Fortiflora, I would definitely recommend doing so as both of these have been shown to lessen the severity and duration of the herpes virus flare ups. I would also consider an upper respiratory culture to make sure that there are no other bacterial causes that may be resistant to the antibiotics currently being given. 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.

Hello, sorry to hear about Gimli. It is really dependent on what kind of infection you kitten has. Most upper respiratory infections are viral which antibiotics cannot treat. Therefor, you must await for the virus lifecycle to end. You may talk to your vet about using lysine gel or topical anti-virals to help shorten the virus life cycle. Hope this helps.
