It sounds like Tigger may have an upper respiratory infection - this is a common cause of sneezing in cats, and may also cause them to breathe with an open mouth for short periods because their nose is congested. I would recommend having him examined by a vet when you are able to - he may need antibiotics to treat the infection. You could also try supplementing him with an L-lysine product such as Viralys - these supplements are available over the counter and can help respiratory infections resolve more quickly in cats.

This is probably an upper respiratory infection. it's very common in cats and is very contagious to other cats as well. It is treated with oral antibiotics for about 2 weeks. if left untreated many cats will end up blind or even die from the disease. I advise going to your vet asap to start the treatment right away.
