DarkSmoke I would still try to take a poop sample to a cat & dog vet like Kathy said and they can test it for parasites or infection, and you would not even have to take the snake in with the poop.
As for starting regurge protocol again, IF you are going to try a solid again and not a liquid(although if it was my snake I would be doing liquid diet right now), then I would suggest:
1) Keep your snake on paper towels if you are not already, this will make it very easy to see when the snake poops or regurges. It may also make it easier to tell if it is a poop or a regurge, when there is no substrate mixed in or stuck to it.
2) Get some NutriBac for that poor thing, the natural good bacteria that is supposed to be in the snake's stomach is probably almost non-existent by now and the natural bad bacteria is likely raging out of control. Out of control bad bacteria could cause more regurges and/or undigested food to be passed out the vent when the snake tries to poop. Even if the shipping to Malta is more than the product, I would find a way to get it, I have seen the NutriBac have a very positive effect on 4 snakes that I have acquired, so to me I feel it is well worth it. Or as Kathy had mentioned before, try using human probiotics.
2) Try the head, but not before at lest 10 days without food and preferably not until the snake has had NutriBac or human probiotics.
Good luck as always.
@ Jase82 females, esp those who will be breeding need to have a bit more weight on them to prepare for breeding, due to the physical demands of egg production, egg laying, they also shed twice during the egg making/laying process, and some will double clutch( lay twice in one season), this all greatly reduces their size and health, so a good heavy, heathly, firm not fat female is better. Males just provide the seed.
