Pawprints in the shower?

The last few days I have noticed some paw prints in the shower - rather large ones actually.  I'm not too sure what attracts Fuji's attention in there? Speaking of Fuji, tomorrow is her last day with us as her mum and dad (aka Sandra and Dave) are returning from their transcontinental travels. Poor Pippa won't know what to do with herself once her best friend goes :(
