RSPCA officers searched property around the tree this morning and believe the cat has disappeared.
Launceston manager Lorraine Hamilton said she found some white fluffy tufts near the base of the tree, evidence the cat might have climbed down by itself.
She said the last anyone heard of the cat's meows was yesterday morning.
A CAT is fighting for its life having been stuck up a palm tree at Ravenswood for six nights, with all efforts to rescue the stranded feline failing.
Ravenswood resident Carissa said she had been trying to coax the cat down from the tree on a vacant property, on the corner of Henry Street and Wildor Crescent.
The Tasmania Fire Service tried for about an hour and a half to remove the black and white cat, without luck.
``We have been trying to throw food up to it . . . and tonight [last night] will be its sixth night up there,'' Carissa said.
``It only comes out of a night - that's when you can hear it.
``We've named it Trouble.''
RSPCA Launceston manager Lorraine Hamilton said the animal welfare organisation would today continue to investigate ways to save the cat.
She said it can be difficult to remove animals stuck at great heights.
``Usually if a cat goes up a tree they can usually get themselves back down,'' she said.
``We don't have the equipment to get right up high.''
