My cat is around 5 and a half years old and usually super healthy... this morning, he started meowing like crazy and acting super weird. He keeps sitting in really weird spots and staring into the distance... he also won't let me pick him up and he\s usually super duper affectionate, especially when I wake up. I will take him to the vet in the next few hours, but has anyone experienced this before? I'm honestly freaking out at this point because he my whole world!
