Ribsy's mama (Ramona) was pregnant when we trapped him from a large feral cat colony. The cats in the colony are exposed to calicivirus, and kittens have less severe symptoms when we vaccinate moms (FVRCP killed) prior to giving birth, and vaccinate kittens (FVRCP killed) between 4-5 weeks old, then with FVRCP modified live at 8 weeks.
We believe some of the cats in/from this colony can be prone to viral gingivitis and stomatitis if they do not receive responsible dental care throughout their lives, so please make sure Ribsy gets his mouth and teeth checked when he goes in for his annual vet check-ups. Drooling, having difficulty eating, weight loss, tongue sticking out and pawing at the mouth are all signs that he may be having mouth pain and would need to go in for an appointment ASAP.
A third pregnant feral came in with Rula and Ramona and helped to co-parent the kittens. She tested positive (IgM titer 1:64, IgG titer negative) for T. gondii and is being treated. Our vets consulted with an internal medicine specialist and a pathology specialist who concurred the risk of kittens being infected was too low to warrant treatment or testing.
