My old cat is 15 years old. Was in the vet in December for bloodwork and a physical and they found nothing wrong. She has started howling and crying at night. First I thought she might be hungry- as our dog steals food and maybe she wasn’t getting enough to eat. Then I thought she might be lonely as we lost our other 2 cats in December so she’s by herself at night.
Now I’m wondering if something is going wrong that the bloodwork did not show. Any suggestions?
She cries around 4-6 am but then sleeps for most of the day but it’s disruptive to my sleep. She goes to my door and cries.
