my indoor house trained rabbit will not eat or drink. he must be force feed baby food, water, pineapple papaya juice for last 3 days. instead of using litter box, he will lay and a clear to white jell is excreted. vet thought he had a blockage from last molting, gave medication. 1 week later was fine, but 2 weeks later the same.it is now the 3rd day. male is 4 years old with no outside contact or any other pets. his diet is fresh greens and timothy hay
-----Answer-----
I would say blockage too, but I see one other issue with him. He needs his pellets and not a whole lot of fresh greens. His diet is likely missing a vital nutrient gotten from pellets, and this is causing his illness

Answer
slowly increase the amount of hay, and decrease the amount of greens. Provide pellets, and hay at all times.
To try and get him to the timothy hay, feed it to him in pressed cubes or rolls. It gives him a kind of toy, and provides the nutrients of his hay.
