Hi, my cat is just over a year old, has been a house cat since we got him and has not been vaccinated.
When he was around 7 months he had constant diarrhoea and was lethargic and his fur went all scraggy. He finally overcome this but more recently has been having trouble with his gums (gingivitis) The vet has given his steroid tablets for the past 4 weeks and today gave him a depo medrone injection. She says it's viral and chances are his sister (who we also have) is likely to have it too. She didn't give it a name, but is she talking about FIV or similar? What does this mean for him? Thank you.
