The bed is big enough for my 8kg cat but its a little wobbly so needs to be against a wall, it comes wall strap. Assembly easy, marked down because some screw holes were full if glue so fiddly digging that off before able to use screws. Pretty good really, sprinkled with catnip and my 2 were straight to it. Its about height of stair banister so not for real climbing cats but my piggy cat don’t climb and ginger likes to hide in the caves which have nice wide openings. Good value for the money.
