Feline Immunodeficiency Virus and Cat Adoption

I work for a local animal rescue organisation that has a high intake of stray cats. Over the last 11 months at this centre we have had approximately eight cats enter our care that have tested positive for Feline Immunodeficiency Virus (FIV). Now considering that we have helped rehome over 250 cats since we opened in October 2016, eight of these animals testing positive for FIV really does not seem like a lot. On the other hand, each one of these animals find themselves in the unnecessarily tricky position of being undesirable to potential adopters, which means their average stay in our care is much longer than those without the infection.

FIV has a similar effect on the cat host that HIV has on the human host, primarily through progressively reducing the number of circulating CD4 T cells which permanently compromises the immune system (Willet et al., 1997). The progression of the infection also follows a similar path to HIV with an acute, asymptomatic, Latent phase which often presents with minimal clinical symptoms (Elder et al., 2010). This stage can last from several months to several years (Elder et al., 2010) and it is likely that most FIV positive cats that are available for adoption will be experiencing this Latent phase. Those that enter rescue in the terminal phase are unlikely to be put up for adoption as by this stage their health and welfare will be greatly compromised in the rescue environment.   

Each cat will have a varied response to the FIV infection, in the same way that humans have varied responses to HIV infection, with some cats more susceptible to difficulties such as oral lesions, diarrhoea or dehydration etc. (Elder et al., 2010). Whether a cat presents with clinical symptoms, and when these symptoms occur, will be determined by the strain of FIV infecting the cat (Elder et al., 2010; ICatCare, 2017), the cat’s genetics (Elder et al., 2010), the cat’s individual immune response as well as the cat’s contact with other infectious agents (ICatCare, 2017). With this in mind it is important that people entering a rehoming centre with the intention to adopt a cat should not be put off by the knowledge that a cat has been diagnosed as FIV positive. In the same way that judgements of a cat’s personality and needs should not be made based on colour alone, potential adopters should not tarnish all cats with FIV by the same brush either.   

The cats that have been in our care over the last 11 months that have been infected with FIV have had completely different personalities and needs from a home. Take our currently available black and white boy Sir Hiss for example, compared to our fully white boy Zulu (who has been adopted). Sir Hiss is a sweet but nervous boy that struggles with human interaction. He is non-aggressive but he will hiss prior to and post human contact, whilst appearing to enjoy the physical touch as he is receiving it. Zulu however was always confident and sociable from the moment he entered our care. Both require an indoor only home as the only cat (unless the adopter already owns an FIV cat) with an owner that keeps on top of any signs of infection or illness, however apart from that these boys are completely different. One is easy, the other is a little bit more complicated, and both will make fantastic pets in the right home.   

People seem to find FIV so concerning and off putting because the name, and symptoms, remind them of the highly stigmatised human infection that is HIV. It is hard for people to separate the two infections in their minds and to put aside the emotional response that may be triggered by the name FIV. Either way people should try to not make judgements based upon a virus or disease, infecting animal or human, as the personality of these individuals remains the same. The management of a cat with FIV may be slightly different from a cat without, primarily with the need to keep them indoors, but every other aspect of cat ownership is the same.

So when you next visit a rescue organisation looking to add a fabulous feline to your family, why not consider the FIV positive cat that will have been brushed aside and overlooked simply because of its condition.
