How long should a kitten with mange be isolated from other cats?

Demodex mange is not contagious so you don't have to worry about the kitten being with other animals. Sarcoptic mange on the other hand, is contagious but it sounds like she doesn't have that. I hope this helps. Best wishes!

Dewormers generally work pretty quickly, I would recommend keeping them away for at least a week. There are several respiratory infections cats can carrier and infections can spread quickly between cats especially from a shelter. That 7 day period will give you time to schedule an appointment at the vet to make sure the kitten is healthy and make sure there is a feline leukemia and aids done to make sure she is negative.

Sarcoptic mange is highly contagious to other pets and even humans. The treatment can take as long as six weeks for your puppy to respond completely and, until then, I recommend limiting your exposure to her and quarantining her away from any other pets until she is recovered.

Hi and welcome to Petco Pet Education Center, formerly Petcoach! I am sorry that you are having to deal with this with Nina. Scabies is a mite that can be difficult to find on skin scrapings and luckily in cats does not often cause them to be as itchy as it does in dogs. I do hope Nina is not extremely itchy and just has the skin abnormalities (ie crusting, scaling or even missing hair). I am glad that you have Nina quarantined from the other cats in your household; however, you may still consider treating them all. Scabies is a mite that can live transiently (ie temporarily) on humans which means we can transport it from animal to animal as well. Treatment can be complete for Nina after just the two injections although sometimes it can take up to four injections. Monitoring her response to treatment, ie if she is currently itchy then her improvement in that; improvement in her skin crusting, scaling and/or hair loss is an indication that the scabies is improving. In addition skin scrapings can be done to evaluate for the mite as well. This will help guide the number of injections needed. Finally, the mite does not live well in the environment; however, the recommendation is to wash or throw out all bedding, in addition to a general thorough cleaning. Please follow up with your regular veterinarian for continued care and to discuss the risk level of the other household cats.

It's difficult to say for certain, since eggs may continue to hatch and the new adult mites could be contagious. At this point it is probably unlikely that there are adults that would be contagious so if your other dog has been treated preventatively I would think it is safe for them to be together. To be safe it would probably be best for you to wear gloves until Waffles's treatment is complete.

Cats with ringworm can remain contagious for about three weeks if aggressive treatment it used, which it sounds like you are doing. I would keep them isolated for at least another week. Keep in mind you will have to disinfect the environment as well because ringworm spores can live in it up to 18 months. I will link a website that details how to do this: http://www.livestrong.com/article/49666-rid-home-ringworm/

I would keep the new dog separated from your old dog as mites are contagious. The ivermectin injection should take care of the mites, however sometimes it takes two or three injections to completely eliminate mites. I would say 3 weeks are probably enough to keep them separate. The doxy will likely eliminate both the Ehrlichiosis and Anaplasmosis within 30 days and your dog should feel much better soon. All these diseases are very hard on your dog, so sleeping is normal. He needs to rest to heal.
