im not positive but i think my tegu is impacted... her stomach is the biggest ive ever seen it and shes walking funny slow and slugish , she fell trying to climb her rock and has been doing stuff she never does like just laying on the other side of her tank where she never goes.... i got her in warm water rite now and i bought mineral oil.... i swear im just gona take the cypress mulch out and use aspen i dont care if its ideal or not at least she cant get impacted well at least i dont think she can.... can a tegu get impacted with aspen? id imagine shed have to eat a lot of it.... maybe im wrong and shes just full from eating a lot of crickets but i dnt know just yet
