unfortunately I have WAY too much experience with syringe feeding - here's a few things I've learned over the last 15 years or so:
1) with most pets you simply MUST make the slurry smell like their regular food or treats that they are used to eating, or you're going to have a hard time
2) using a mixer, blending their pellets with water (add just a little water at a time) is almost always easier to get them to eat than any specialty food they aren't used to, and almost always as nutritious and almost always much cheaper
3) we don't bother using an oral syringe, instead we use a luer style sryinge (the type with the twisting end for injection needles) and drill out the center of the tip with a small drill bit (it's very easy to do by hand, usually no need for a drill) creating a much larger orifice which allows the slurry to be thicker and flow out much easier (which in turn is much safer)
4) if assist feeding them is going to be done on a routine basis, don't bother wrapping them up - in our experience this only angers or even frightens them; instead, make the slurry so delicious they want to eat it as a treat and you won't need to secure them in any way at all (with a little trial and error you can make it nutritious and delicious)
5) if you have a multi-pet household, it's sometimes easier to give the other pets some of the slurry too, without any medications of course, instead of separating them while eating if they're accustomed to eating near each other (try to make it as normal as possible). This also helps for any future needed assist feeding, if a different pet gets sick, because they'll already be used to doing it.
6) if at all possible, do it on the floor (again, keep this as normal as possible) and expect it to take a few minutes. Let them take a short break if wanted and then finish up the syringe a few minutes later.
7) if the medicine tastes or smells weird, "Mary Poppins" it (a spoonful of sugar makes the medicine go down; for cats we use stinky fish, for buns we add different herbs/vegetables/wheat grass - a few small mint leaves work well for us)
8) time of day matters (you know your pet and you know when they're most likely to be hungrier, use that to your advantage)
9) always tap out the air bubbles - best case scenario it makes a big mess when the syringe "burps", worst case scenario you could aspirate your pet
10) once the syringes start squeaking or sticking, throw away the plunger half (or risk squirting massive amounts in their mouth at once and possibly aspirating them) but keep the cylinder half and use it with a new plunger half so you don't have to redrill another hole
11) if it's going to be ongoing, buy them in bulk online for MUCH cheaper than you'll likely find them locally
12) often times you can get pets to eat the slurry off of their bowl/plate if they watch you squirt it from the syringe, yet they sometimes won't eat it if you squirt it without them seeing you do so (maybe our pets are just weird like that, I dunno)
13) it's a bit of a learning curve, but it's a short curve and obviously worth it - when done properly, your pet just thinks they're getting a special treat and will usually enjoy the feeding
14) it's easy to do, you just have to be careful and go slow until you and your pet get the hang of it (usually after just a few times)
And she's even nibbling on hay which is great. She was extremely excited about dill leaves and basil, and was clambering all over me to get them. She lay down next to me for me to pet her which she hasn't done for days too so I'm hopeful she's on the mend 
And I've got far more critical care stuck to my clothes than got anywhere near her mouth! I've tried putting it on the fresh food but she just nibbles around it 
you'd think apple and banana flavour on a piece of apple would be acceptable but apparently not.
