I'm so sorry to hear that Boo Bear may be senile. It's heartbreaking to hear them meow so much and not knowing what they want. I hope something can be done to make him more comfortable.

Many of the things you describe fits on Fister, too. He meows quite a lot during the night and now also in the daytime. He just wants me to come and sit/lay next to him, then he relaxes for a while, but will start again later. He is not even 14 years old.

I will certainly ask my vet about this.

Give Boo Bear some snuggles from me!
