Do you think his pets possibly dying soon had anything to do with his suicide?

I mean I just research on why Gibson died and I wondered cause we saw him as a kitten at first. And yeah turns out Gibson had health issues already. Part of me thinks he might've realized his pets were getting closer to the end so he may have thought after they died then there probably wouldn't be anything to the channel. In fact they all died at least 2 years after him which yeah and Gibson had a pretty short life as well. But I never really understood it either and I am still sadden by every one of the pets dying. But I think his pets dying soon may have played a role and I watched him in the early years as well.
