Rose ( A Rose by Any Other Name ) A Big Ball of Fluffy Wuffly Cuddly Wuddly Stuff ( or Rose for short ) was a cat the Tenth Doctor adopted after Rose Tyler was trapped in Pete ' s World . Rose , K9 , and the Doctor uniquely lived together without any other long term companions . Rose - the - cat would often try to help the Doctor cope with the loss of his former love , through various means . Most to all of these failed . Despite this , her time on the TARDIS did note a sharp contrast in the performance and character of the Doctor . While he would initially avoid leaving the TARDIS or having adventures at all , by the time she left he was not only actively seeking out trips once again , but he also eventually decided it was time for him to take on another companion . Rose eventually left the TARDIS team , searching the cosmos for a new person to comfort as the Doctor decided it was time to find a new companion . After an immeasurable amount of time in stasis , Rose emerged to find the real Rose Tyler standing in front of her pod in a state of confusion . Biography . The Doctor adopted Rose during a fit of depression , and named her after his now - lost companion Rose Tyler . Owning a cat was initially far from what the Doctor expected it to be . Directly after bringing her into the TARDIS , Rose scratched the Doctor up and ran off . The Doctor would not see her for five days . When he did see her again , he lectured her for being " a bit rubbish , " but Rose mainly ignored him during the conversation . The Doctor at one point spent an entire day sulking in bed and crying over the loss of Tyler . Attempting to cheer the Doctor up , Rose - the - cat managed to pilot the TARDIS to various locations in space - and - time to track down animals to hunt . She then presented their carcasses as gifts to the Doctor , which only made him more sad over the death of all of the various creatures . Rose did not comprehend why the Doctor was not grateful for her hard work . The Doctor in another instance entered his closet to discover that Rose - the - Cat had pulled down all of his suits and sat on them , leaving them covered in neon hair . The Doctor planned to travel to Deva Loka to relax , but discovered that Rose had scratched up his long brown coat , ruining it . Enraged , the Doctor left Rose dangling outside in a space - suit as he considered how he was nowhere near as merciful as he used to be . Rose eventually began to warm up to the Doctor ' s presence and accepted him as her owner . Rose at one point asked the Doctor if he had ever had any other pets in the TARDIS , to which the Doctor admitted that there was someone that Rose needed to meet . That " someone " was a personal version of K9 which the Doctor kept on the ship . Standard for most dogs and cats , the pair did not get along . Their first encounter ended with Rose attacking K9 with the Sonic Screwdriver and K9 entering " defence mode . " The Doctor once again resulted to leaving the two dangling outside the ship as punishment . While walking together , Rose - the - Cat suggested that the best option for getting over Rose - the - Human was for the Doctor to get a rebound companion . The Doctor was initially reluctant , but eventually agreed . The night of his " blind date , " he stormed back into the TARDIS exclaiming that he had been stood up . In fact , his potential companion ( a member of the Sisters of Plentitude ) was in the TARDIS petting Rose - the - cat . Upon seeing this , the Doctor angrily reminded Rose - the - Cat that they were there to find a new companion for him . Afterwards , the Sister asked if she needed to leave . Rose at some point was infected with flea s , and while the Doctor was initially playful in teasing Rose ' s newfound " friendships " , he eventually realised that it was becoming a serious health hazard for the feline . Refusing to use regular flea cures ( which would " upset the natural balance " ) the Doctor took Rose to a planet made entirely of candy floss surrounded by a gas that was irresistible to insects . The Doctor placed Rose in the stuff and successfully cured her of her pestilence , but doing this also shaved most of the hair off of her lower body . In a " genius " solution , the Doctor put Rose in a miniature blue suit much like his own . While the Doctor and K9 were amused by the situation , Rose was not . Rose and the Doctor eventually parted ways , with the Doctor deciding that it was finally time to find a new companion . Rose joined an " agency " which would send her through the universe looking for another heartbroken soul to comfort . After travelling for an immeasurable amount of time in stasis , Rose emerged from her pod to see her namesake standing directly in front of her . Amused , Rose - the - cat asked Rose - the - human if she was a fan of " Chums " . ( COMIC : " A Rose by Any Other Name " ) Personality . Rose - the - cat was , by no one ' s standards , human . Rose would often have trouble understanding the Doctor , partially because of his insistence on never moving on from his past , but also mainly because of basic misunderstandings which fell from her being a cat and him being a Time Lord . Rose would often only think of herself when making decisions . While she often encouraged the Doctor to move on and find a new companion , it was more often than not because she found his constant ranting and bickering to be annoying . She was easily bored and easily annoyed , and she would never try to hide how she felt . Rose showed a surprising lack of concern for the effects of time travel , and she would often cross her own timeline simply to avoid mildly annoying circumstances or events . She at one point sent a shockwave of paradoxes across all of time - and - space in an attempt to create a cat flap in the TARDIS ' wall . While Rose often would approach the Doctor with plans for dealing with his lingering emotions for Rose - the - Human , the plans would often be things that Rose simply wanted to do anyways . One one occasion , Rose hijacked the Doctor ' s blind meeting with a potential companion for the sake of attention . In other circumstance , Rose suggested the Doctor start a band to work out his feelings . The mission was a success , but Rose still attempted to revert the band ever being created simply because it annoyed her . ( COMIC : " A Rose by Any Other Name " )
