The combo test for FeLV and FIV is a must. They are not that costly too. These are deadly transmittable diseases.

Even with a NEG/NEG combo test:

Isolate the cat for 10 days, longer if URI symptoms persist. (at least 3 days after last symptom)

Other common ailments include: distemper, fleas, worms, ringworm, URI, UTI.

I'm not sure if your other animals can contract any of these. Apart from the fleas, which I know everybody can get.


Good luck with the kitty, thanks for helping.
