I wouldn’t worry unless they’re showing signs of pain(Meowing without reason, trying to rub eyes but then yelps or jumps in pain, etc.) or signs of blindness (Running into furniture head on, getting confused if you move a piece of furniture and running into piece of furniture, etc.) And my kitties do this all the time. Usually there’s several reasons why this happens. 1) They have something in their eyes such as goo from sleeping, almost like eye boogers, 2)They are really tired and might have allergies or a cold, 3)They love you (Cats don’t like looking straight into your eyes, they like to almost squint in love, and looking from the corner of their eyes and slow blinking it shows that they love and respect you) 4)They got something stuck in their eyes. If I were you I’d first go and examine their eyes yourself. Check for eye boogers and wipe it away gently if its there. Kitty won’t like this but it has to be done. Look for something in your kitty’s eyes. If you see anything ask yourself if this is something you’d be willing to take out of a child’s eye or something you’d take the child to the doctor for. If it’s something you’d be willing to take out of a child’s eye, first go and wash your hands with soap and water, clip finger nails down so you don’t accidentally poke kitty’s eye and then gently remove the object from the eye. Read kitty’s signal to determine if your kitty is simply angry with you trying to take this out of their eye or if they are crying in pain. If kitty is simply meowing in complaint, continue. If kitty is doing anything and everything to get away from you and is screaming DO NOT continue. Take time to reconsider if you accidentally poked kitty’s eye or if the object is lodged in the eye. If it’s lodged, go to the vet. If you simply had an unsteady hand, you can try again. If you don’t feel comfortable trying again maybe ask a friend to come and try, or simply go to the vet or a pet clinic. If there is nothing in the eye, or if there was eye boogers, wait a couple days and monitor their activity. Do they show signs of sickness, are they sleeping more? Sneezing? If they don’t show any signs, have changes in urine or stools, or change in appetite, but they do show signs of a human like cold they most likely just have seasonal allergies or a little cold. Don’t fret, its not something to be worried about for now. Do a quick google search for some pet safe allergy solutions, my vet has told me that some human medications may be a cheaper but still safe alternative to pet medication. I would do your research and find out what would work best for the symptoms and size and age of your cat. If the cold worsens or more symptoms appear maybe post on here again, and or go to the vet. Just use your best judgement. If there is no sickness, and nothing in their eyes, no signs of blindness, your kitty simply loves you and you need to brush up and learn about kitty language. Cats are subtle creature and demand and need you to know how to read their body language. Cats tell us everything we need to know if we only do our homework and learn to speak cat. They tell us when they’re hungry, that they are mad, happy, sad, in love, afraid, in pain, need the litter scooped, and much more. Do your research and your kitty will be the happiest kitty alive. I hope this helps, let me know if you need help, you can contact me at: emmakat8@live.com
