Abviously not. Hence tha pupils changing size.
yes they do
Cats pupils adjust just a little slower than humans pupils.Actually the answer above is not correct at all. Cats eyes adjust almost faster than humans. The reason being, because they are going to fight or are scared/frightened there pupils grow on will. If the room is too bright they pupils will grow to very thin slits. When nothing is wrong with the cats there pupils are normal, like a perfectly smooth rhombus.
Are you talking about the pupils look straight in the am and then look like a circle in the afternoon? This could possibly be do to constriction and dilation of the pupils with adjustments to how light it is out....
It helps the pupil let in the right amount of light.
because some cats have a weird history like heritage problems and it causes them to have round pupils, especialy if its a big cat like a Maine coon or a Persian.
Like many animals, cats have large pupils (slit pupils in domestic cats) and a tapetum lucidum, a tissue layer behind the retina that reflects light back through the optical sensors. These improve their night vision. (The tapetum is the source of cat's "glowing eyes" at night.)
Cats eyes can spot predators because they have large pupils which adjust to darker situations easier. This allows cats to spot their prey in dim conditions.
Cat's pupils enlarge when there is low light and when they are excited by something. Typically when they see something surprising or that they consider prey, their pupils will enlarge. There is no reason to think that they are seeing ghosts when this happens.
there pupils are getting bigger
Cats have the ability to see more equivalent than humans because of their eye shape. They do the same things as humans though. When its dark the pupils grow large. When its sunny they can make the pupils smaller too.
As a cats eye pupils dilate in the dark, letting in more light, they are very good at seeing in the dark.
Cinderpelt has brown eyes in the Warrior Cats series.
No nothing is wrong with your cat, her pupils are wide because when any object with eyes looks at a bright light, their eyes get small. But when it's dark, the pupils get big. So know you know why. :)
