WE got to know about FiE because of our pet food supplier, J. A kitten she rescued (J does rehoming and does not sell live-pets , which is why we're proud to buy from her) got horrendously sick, and it was FiE - which nearly killed the little one too. J has decided to keep the little one, and named him Sunshine. Sunshine was lucky. FiE is more of a kitten disease, like FeLV and FiP. So please take note for the little ones in your care.

What is feline infectious enteritis (FIE)? FIE is a small, hardy virus that was thought to be almost eliminated from the cat population because of vaccination. It attacks the infected cat's gut and causes brain damage in unborn kittens.
Which cats are vulnerable to FIE? Kittens are most susceptible, especially when the protective antibodies they receive in their mother's milk have waned. This is usually between 4-12 weeks old but, in exceptional cases, it can be as late as 20weeks. Unvaccinated adult cats are also susceptible and allowing booster vaccinations to lapse may be risky.
How do you prevent FIE infection? The main method is by vaccination. Kittens are normally vaccinated at 9 and 12 weeks of age, although any cat can be vaccinated and older cats may respond to a single dose of vaccine. It is usual to give boosters every year with cat 'flu vaccines. 'Flu vaccines need to be boosted yearly, but FIE boosters can often be given only every other year.
