It's very easy, just click on the food item you want to feed to your pet in your inventory, select "Feed to (insert pet name here)", and it's that simple. :)
No, but if you place a Petpet next to a food item and leave it there for a while the Petpet will eat it. Also you misspelled "Jetsam".
You can trade them in the neggery or, let your neopet(s) eat them.
yes i have neopet on my neopet id
It depends on your Neopet, some have different tastes. Some won't eat half-eaten food like pizza or omelette, some won't eat 'gross food', Glowing Jelly is another food they might not like. Even Skeiths can be picky, despite being able to eat any item.
You can't make your neopet drink it, It's a Battledome item, equip your neopet with it!
Use a Transmogrification Potion on your Neopet, you can only get them via Random Events however, but they are very rare though.
You can't make your Neopets look angry on your Userlookup. The only way for your Neopet to look angry is at the Battledome, or using a Mysterious Cape with Cowl. You can see what it makes your Neopet look like below.
