Question about whether or not this is haram?

I don't think so.

But I'm not 100% sure.

I don't see no reason why not.

how does feeding of your snake correlate with fasting during ramadan?

oh.. it's probably the same like coming into a sandwich shop and ostentatively asking what are the meatballs in meatball sandwich made of, because you do not eat pork... when there are three or four obviously non/pork versions of sandwich filling.

aka. stirring troubles

fasting rules do not apply to your snake, anyway.

even if they would, feed him before ramadan, and after. it will make it easily, snakes can starve for months, if in good condition at the beginning of starvation.

regarding the rats, if there should be a problem about them during ramadan, remove them for the duration of festivity.

if there is a general problem with having ïmpure"animal of some sort, either get rid of the animal that needs them in its diet, or get rid of religious dogma.

If you're comfortable breeding rats in your room, that's your thing.

Why would you expect to find a ruling on this? No, of course there's nothing about it in the Quraan = Not Haram.

I don't think it would be haram... I'm no expert though...
