> My moral framework requires consent from human beings as for other creatures i see no problem experimenting with them as log as we put in the best effort possible in reducing their suffering in the process
Consent is only possible in high-functioning adult humans though. I would expect you would make the concession that 'valid consent' would exclude very young and old humans and the intellectually disabled. But they are no different in this respect to members of other species that can't (or wouldn't if capable) give their consent.
If you see no problem in inflicting suffering on another conscious being that is non-human then why is reducing their suffering even important to you? If it is important, then why isn't it as important as the suffering of a human of reduced intellectual function?
> If you're going to qualify all creatures on the same level then we shouldn't be experimenting on lab rats either don't you think?
Yes, a consistent moral framework would likely agree with this sentiment, assuming consciousness and the ability to suffer is the important consideration.
> We shouldn't be killing all those malaria spreading mosquitoes either since their creatures too right?
Well that is the position of adherents of Jainism [1], but it does really depend on what test of consciousness and capability of suffering you think is necessary to meet, rather than whether something is simply a 'creature'.
