Can any one explain Pseudomonas Infection. My bengal has terrible sinus issues and has finally been diagnosed with Pseudomonas. What type if infection is it and where does it come from? His primary vet is out of the office today so she can't provide answers. To tell you the truth I get better information off of this site. He will start treatment with Baytril today. It's been a long road and if I can prevent a re-infection I'll do what ever I have to. Thanks
