Iv'e got gorilla glue, what would thin it?
Not sure, but it doesn't have a solvent-smell, so I'd try water. You can buy insulin syringes at a pharmacy without a prescription in most states. I buy them buy the box -- (I remove needles and use them to medicate my birds). Mine use minute needles and are probably to0 small to handle glue... but a regular insulin syringe might do the trick. Or, if you have a decent relationship with your vet, ask if you could purchase a larger syringe/needle. Or you could use a tiny straw, like a coffee stirrer.
