Alright, I am not an expert, but here's what I have know/have learned: I think it depends on the cause of the URI-- which with cats, we know it can be many different things and usually, it's too expensive to actually run a culture and find out what is causing the URI (unless it's a chronically suffering cat having a significant amount of trouble and then the cost outweighs the need). In cats, it's usually feline herpes (a VIRUS) OR feline caliciVIRUS causing the URI (but not always). In general, viruses are not zoonotic (transmittable over different species). However, if the URI is caused by a BACTERIAL infection, then yes, possibly it is transmittable to a dog. Again, in general though, cats are more prone to URIs than dogs. I think dogs most common shelter-type, highly contagious disease is 'kennel cough.' Here are the 'general' rules: There are some zoonotic diseases that can be transmissible between cats, dogs, and humans, but they shouldn't cause upper respiratory diseases. Most are caused by internal parasite infections, such as giardia or tapeworms. Rabies, mange, and ringworm are other examples of zoonotic diseases. For cat and dog upper respiratory infections, however, the disease-causing agents are usually species-specific (hence the titles being "FELINE herpes," etc., and your dog should not be able to catch the URI from a cat. If a dog seems to come down with a URI at the same time as a cat with a URI, (insert my lawyer-speak here), "it's more likely than not" that the dog may have actually caught it from another dog. Here's a quick reference for shelters found on the internet: http://www.animalsheltering.org/resource_library/magazine_articles/jan_feb_1997/controlling_upper_respiratory_infections_in_your_shelter.htmlOkay, again, I am no expert, but this is the information on the subject that I have found generally.Caroline
