If she is young or is undergoing a lot of stress (moving, new animal or person in the house, change of schedule) the most likely cause is a viral upper respiratory infection. Many cats will get by with the following support - lysine supplement- try Vetoquinol Viralys (L-Lysine) Oral Gel for Cats - treat all cats as directed on the bottle until all cats are well - try wet food or soaking kibbles and then very slightly warming the food. Cats are very smell-driven and warm wet food is smellier and more likely to be eaten by a stuffy nosed cat. - recommend a probiotic such as purina Fortiflora for every cat in the home. Odd as it sounds, we’ve found that probiotics actually speed recovery from URI’s - if any cat is squinting an eye or thick eye discharge, refuses to eat, or becomes lethargic, it’s time to see your vet. These are signs of eye ulcers and/or secondary bacterial infection. These cats will need eye ointments or systemic antibiotics. Occasionally, nebulizations or more aggressive treatment is needed. If Mama is lethargic, has decreased appetite, or the nasal discharge is thick, yellow/green, or bloody, or she is breathing with her mouth open, she needs to see the vet as these could be something more serious such as fungal infection, cancer, or secondary infection. Best of luck to you and Mama.
