My senior cat is requiring hand feeding and after struggling with the nonsensical 10 ml stubby tip medicine syringes the vet gave me, I ordered these. They are easy to fill using a mini funnel, and the plunger goes in easier than in the 10 ml syringes too. The only warning ⚠️ if you're using these for cat feeding, the tip opening is bigger so more food will come out of it. Be cautious until you get a feel for these larger syringes. Because the opening is larger too, you can make the wet food mush just a bit less watered down, perhaps boosting the nutrition per feed. If you are looking for these because your pet has come to a point of having to be syringe fed, I hope for healing strength to shine around you both.
