Lately we've noticed that our elderly cat Tori is not able to see very well anymore. Her pupils are always huge, like they are trying to take in as much light as possible. When she walks toward something she veers off at the last second before she bumps into it so we know she's not completely blind. Plus I think she is getting hard of hearing too. She won't acknowledge any sounds and won't respond until we touch her.
We've got her in 1991 when she was just a kitten so she's 18 years old now. It breaks my heart that her time with us is slowly coming to an end. She was and still is the best cat we owned. She still eats good and hasn't lost any weight yet. I just hope she stays healthy and with us for a while longer.
