Actinidia Kolomikta

Can anyone help? I'm quite new to the world of gardening and last year I purchased a Actinidia Kolomikta. I didn't expect anything to bloom or climb last year but did notice that once planted it started to climb until the leaves turned brown. I thought it had died but my brother in law suggested moving it as he thought it may have become waterlogged in the position I had planted it. A few weeks ago I noticed healthy leaves growing but once again the top leaves turned brown. Although the bottom leaves appear healthy. I have heard cats take a liking to this plant. Could this be the problem as I'm often visited by next door's cat?
