Young Pallas's cats often die of toxoplasmosis

Pallas's cat is a popular zoo species. They are endangered in Central Asia but they are fairly numerous in zoos where they are bred. They've encountered breeding success but the kittens frequently die from acute toxoplasmosis, an infection of the Toxoplasma gondii protozoan.

A study entitled: 'Toxoplasmosis in Pallas' cats (Otocolobus manul) raised in captivity', reported that a breeding pair of Pallas's cats in Schönbrunn Zoo in Vienna, Austria produced 24 kittens between 1998 and 2002. Sadly 58% of the kittens died mostly of acute toxoplasmosis between the second and fourteenth week of their lives. The study was published online by Cambridge University Press on 21 October 2004. This problem has been known for a long time.

They decided to develop a strategy to protect the cats from fatal toxoplasmosis. The shed T. gondii oocysts of one 12-week-old Pallas's kitten were bioassayed in mice. This means measuring the concentration of oocysts. Toxoplasma gondii was isolated in tissue culture inoculated (vaccinated) with tissues of the mice.

The researchers stated that the surviving kittens (presumable those that had not died of toxoplasmosis but were infected with the disease) were treated with clindamycin for 16 weeks. Clindamycin is an antibiotic. It fights bacteria in the body. Toxoplasmosis is a single celled protozoan parasite. But the antibiotic 'seroconverted' the infection. This means that the presence of the disease in the blood was eliminated i.e., a conversion from seropositive to seronegative.

"Clindamycin is indicated for Toxoplasma and Neospora infections although in human medicine sulfadiazine and pyrimethamine remain the drugs of choice for toxoplasmosis. Clindamycin is one of several suitable drugs for treating chronic rhinosinusitis in cats." - Science Direct.

Comment: there is a dramatically sad and uncomfortable backstory to the cute Pallas's cats that zoo visitors see. Are we okay with the fact that so many kittens die of toxoplasmosis and is the infection being controlled in 2022?

Pallas Cat Domestic Ownership California

The title is a rather clumsy phrase used by people searching for information about keeping the Pallas cat in California as a pet.  That is my reading of the search term.

Without going into lots of detail as to why it is inappropriate to keep a Pallas Cat as a pet in California, suffice to say that the keeping of a wild animal by individual person is banned in California.

There is one qualification.  If the person owned the animal in question before in 1992 they are allowed to keep the animal until I presume the animal dies.  In 2014 that would not be applicable to any wild cat species because none of them live beyond an absolute maximum of around 20 years.

Most often small wild cat species in captivity die relatively young because they are unsuited to that sort of lifestyle. Private zoos and public zoos have great difficulty in maintaining their stock for this reason.

The Pallas Cat is very cute looking and quite a few people think about having one of them as a pet but it won't work and it is not good for the cat. Even wild cat species known to be quite amenable to being domesticated are a handful and will challenge even the most dedicated exotic pet owner.

Below is a map from the excellent Born Free USA website which provided information about the banning or otherwise of exotic pets on a state-by-state basis:
