Question 1

A cat tests positive on FIV ELISA. The cat is 8 weeks old and was born to a seropositive queen. How should this result be interpreted?

Accepted Answer

Likely maternal antibody transfer; retest after 6 months of age

Answer

FIV ELISA detects antibodies, and kittens can carry maternally derived antibodies until 6 months of age, yielding false-positive results.

Microsporum canis

Answer

Microsporum canis accounts for approximately 90% of feline dermatophytosis cases and is also the predominant zoonotic species from cats.

Toxoplasma gondii is a leading cause of feline uveitis and should be tested via serology when FIP is ruled out.
