My indoor only 10 month Kitten jumped on the lid of the laundry basket which collapsed with her weight (I managed to catch her ) she also ran into the pateo door whilst chasing a ball and I also managed to catch her when she was snoozing and fell off the sill (still not sure how she managed that however saw the pillow slip and she must have fell with it ! That was all today ! Hubby is always saying we should let her go out so I reminded him if she is this clumsy inside can you imagine her out there !!!
