Hi thank you for your advice. The label does say 0.5 on the bottle but in my instructions is says differently. Have you given your guinea pig 0.5 twice a day for example and did you find this to be effective for pain relief? Many thanks
It breaks my heart to hear of your situation, but this is my last post on here because for reasons unbeknownst to me, this forum is very strict with members giving out dosage suggestions, even when the internet is filled with (ok, filled is a strong word as there are about ~10) clinic studies discussing efficacy of meloxicam on guinea pigs.
I'm going to be beyond even mind blown if the mods take this down, but this is from DVM360. - literally a source of truth for vets.
Maybe take this to your vet? Pharmacotherapeutics in small mammals (Proceedings)

"Meloxicam is probably the most commonly used NSAID used in exotic small mammals, and is available in both oral and injectable forms. Its primary action is the inhibition of cyclooxygenase-2, which mediates inflammation. Meloxicam at 1 mg/kg SC dose reduced acute post-laparotomy pain behaviors in rats, but a 0.5 mg/kg SC dose was not effective. In another study, the pharmacokinetics of single or repeated PO doses (daily for 5 days) of either 0.3 or 1.5 mg/kg meloxicam in female rabbits showed that after single oral dosing of either dose, maximal plasma concentrations were achieved at 6-8 hr and were nearly undetectable by 24 hr. No drug plasma accumulation was identified at either dose after 5 days, and meloxicam was rapidly eliminated after drug discontinuation. Meloxicam administered 0.5 mg/kg PO produced significant analgesia in visceral pain tests in guinea pigs. These studies suggest that some rodents and rabbits may need higher meloxicam doses, but further research is necessary to determine appropriate meloxicam analgesic doses and dosing frequency in small mammal patients."
I tried doing the maths for you but the post was edited. Sadly, you'll have to do your own maths or have your vets do your maths for you. Dosage information has since been revised in newer literature but again, I'm not allowed to share....
Here is one such link you can share with your vet, I guess?
Managing pain in zoological companion animals
"From there, doses tend to be higher; chinchillas and guinea pigs are administered 0.5-0.75 mg/kg every 12 hours, rabbits 1 mg/kg every 24 hours, and rats and mice 1 mg/kg every 12 hours (Fredholm et al. 2013; Delk et al. 2014)."
You/your vet need to take into account strength (above), cat meloxicam strength, and convert mg/kg into mL. As I was pulled aside, I am not, sadly, allowed to calculate that for you guys but your vet can easily do that.
Best of luck to your piggies!
