Thank you for your patience. There are quite a number of possible causes for Purr-La's eye discharge, lethargy and bad breath, including anything from an upper respiratory infection, to bad dental disease, or even an internal organ issue such as kidney disease, or even an endocrine problem like diabetes or hyperthyroidism. Because Purr-La is now classed as 'senior', we certainly have to consider conditions that effect older cats.
Hopefully your girl is drinking water with no issue, and if she isn't then definitely try to encourage her to. If she drinks wet food, feed her this only for the next few days. Try to carefully wipe the discharge from her eyes if you can, and keep her warm and comfortable. If you can keep Babbette away from Purr-La's food so she can eat in peace, that will also be very important.
If this lethargy and bad breath has been the case for several days, I would really encourage you to visit your local vet tomorrow morning if you can. Here they can carry out a full physical exam including a careful oral exam to check her mouth and teeth (for signs of dental disease). I would also recommend a full senior cat blood test to rule out potential issues like diabetes, hyperthyroidism, kidney disease and liver disease.
Best of luck with Purr-La and hopefully she improves overnight, otherwise do get her seen in the morning if you can. I hope all of the above makes sense?
