Protect your pets from SARS-CoV-2 infection

Cats are susceptible to SARS-CoV-2 by a reverse zoonosis. If you have COVID-19 you can infect your pets.

Our team confirmed this finding in a seroepidemiologic survey* of cats and dogs in Portugal and found antibodies against SARS-CoV-2 in 15/69 (21.74%) cats and 7/148 (4.73%) dogs.

As in people, animals often have mild clinical signs, or are asymptomatic, but there are also reports of fatal cases. 

Why testing

By performing this test will allow you to know if your Cat has been infected with SARS-CoV-2. This test detects IgG antibodies against SARS-CoV-2 Nucleoprotein (NP)  and Spike (S) protein. 

Please note, that IgG antibodies arise 2-3 weeks after infection and are maintained for some months.

 Main conclusions of the study:

 - Cats that lived in COVID-19 positive households are at more risk to be infected with SARS-CoV-2  and some cats can become ill or may die. 

- Cat to cat transmission of SARS-CoV-2 is also a possibility. Cat that lived in COVID-19 negative households but lived in free range and contact with other cats also tested positive.

 - If you test COVID-19 positive please avoid direct contact with your cat, or ware a mask. 

- Serological testing should be performed  2-3 weeks after contact with a COVID-19 positive case.  

- One to 2 weeks after contact with a COVID-19 positive case a molecular RT-qPCR is recommended. Please check more info about molecular tests for cats here .
