Digestion/ Loud Stomach

If you’ve seen my previous thread you’d know my rabbits stomach is always gurgling. Has anyone tried these (i’ve inserted a link but they’re called oxbow natural science digestive support for small animals) and do you recommend i get them? I’ve read a lot of reviews and 99% are positive, some said too that it’s helped with the sound of their rabbits stomach. Just wanted so extra guidance before i buy them.

Can you tell the diet and if he is drinking from bottle or bowl? But Oxbow if OK.

Gurgling guts are not normal, so I would suggest keeping a close eye on his food intake and poo output and ask your vet for advice. He should be eating mainly grass or hay - the fibre keeps the teeth worn down and the digestive system working normally. Pellets are not essential, and should only form a very small part of the daily diet. Any dietary changes (except hay) should be done gradually.
