Ours is about 3.5 months old now and with instrucions form the vet we had to give ours meds and fluids with a syringe. We also just mashed up a few crickets and mixed with a little pedialite. Drew into the syringe and gave to himThat didnt go as well as just fluids. Luckily he got his appetite back.
Here is how the vet did it and how we did it. The vet used his pen intto the corner of his mouth. My wife did it by starting his lips with her finger nail and then just slid her finger in his mouth (to small to bit hard but sure surprised her the first time) Instead of squirting the fluids into the back of the throad I would drip in the bottom of him mouth there is alot of room where the tongue is.
Just give enough that it dosent run out then allow him to swallow. I was able to get probably 8 ish drops in and he would swallow it all. Figure when they lick up water that is a pretty good amount and we did that 2x a day. His antibiotics dosage was 1 drop,, after checking with the vet we added several drops of pedialite with it to hydrate at the same time.
To also help with hydration, we moved his cage into the bathroom where we could turn on the shower aqnd steam it up real good and just the door and keep the humidity extra high. plenty of misting with warm water as well.
Our little fella is just back to eating on is own as of yesterday and was back on the hunt ageressivily as well. If we hadnt gone to the vet I doubt he would be with us much longer.
Best of luck!
