Animal Hospital just got a new helper, and players cannot stop talking about him. Sam is a calico cat who shows up after the chaos of a Slime Shift. He wears a bright yellow hazmat suit and carries a scrubber, ready to clean up the mess Slimebert leaves behind. If you have survived a Slime Shift and are wondering who this new cat is, we have everything you need to know.
Who Is Sam
Sam is a minor NPC in Animal Hospital, but he quickly became a fan favorite. He has a white face with an orange patch on one side and a black patch on the other, giving him a classic tri-coloured calico look. His pale blue eyes have narrow pupils, and one of his tiny pink ears looks bitten, which hints at a rough past.

His outfit tells a story of its own. Sam wears a yellow hazmat suit with black trim, blue gloves, a black utility belt, and boots. This look strongly suggests he once worked for the Animal Corporation on the Hazmat Team, before getting fired. Despite that setback, he shows up at the hospital ready to work again. That says a lot about his character. He is practical, hardworking, and willing to take on the job nobody else wants.
When and How Sam Appears
Sam does not show up right away. He appears after you complete the Slime Shift, which begins on Shift 12 with the arrival of Slimebert. Once your team survives that shift and clears out the slime, Sam walks in and asks if he can work at the hospital.
He stays available between Shifts 12 and 23. If you miss him during that window, you will need to wait for another slime encounter to see him again. This makes timing important if you want his help early in your playthrough.
How to Hire Sam
Hiring Sam is simple once he appears. You need 250 Animal Coins to bring him on board. After you pay him, he joins your team and gets straight to work.
Here is what happens once Sam is hired:
- He automatically cleans any slime left in the hospital.
- He checks rooms and removes Hiders before they cause trouble.
- He puts out room fires without you needing to ask.
- He stays for three full shifts before leaving on his own.
That three-shift window is short, so make the most of it. Use those shifts to focus on treating patients while Sam handles the cleanup work in the background. He genuinely takes pressure off your team during a hectic run.
Why Sam Matters for Your Runs
We have played through the Hazmat update ourselves, and Sam changes the pace of a shift completely. Before he arrives, players have to juggle patient care and slime cleanup at the same time. That splits attention and slows everyone down. Once Sam joins, one less task competes for your focus.

His ability to clear Hiders is especially useful. Hiders can disrupt a shift if left unchecked, and dealing with them manually costs time you do not always have. Sam removes that problem without you lifting a finger. If your hospital is dealing with fires in multiple rooms, his automatic response saves you from running back and forth.
Three shifts might sound short, but they often line up with some of the toughest stretches after a Slime Shift. The hospital still carries slime residue, and anomalies tend to linger. Having Sam around during that recovery period makes those shifts noticeably smoother.
Sam and Slimebert: The Connection

Sam only appears because of Slimebert, so understanding that anomaly helps explain why Sam matters so much. Slimebert is a massive creature made of neon green slime, with two eyes on uneven stalks and a wide black mouth. He shows up during the Slime Shift and eats anyone who gets too close, causing serious Sanity loss.
Slimebert cannot be killed with weapons. Tasers and firearms do nothing to stop him. The Fire Extinguisher, tied to the new Firefighter Class, can stun him temporarily, but he will not disappear until the shift ends on its own. The safest strategy is simply avoiding him. He moves slowly and does not chase players, so staying alert and keeping distance works well.
Once your team survives that ordeal, the hospital is left covered in slime. That is the moment Sam steps in. His entire role exists because of the mess Slimebert creates, which makes their relationship feel intentional rather than random.
Tips for Making the Most of Sam
A few small habits can help you get full value out of Sam during his short stay.
- Save Animal Coins ahead of time so you can hire him the moment he appears.
- Focus your own attention on patient treatment while he handles cleanup.
- Watch for his clumsy animations, since they do not affect performance but are fun to notice.
- Plan your next few shifts around his three-shift timer so his help does not go to waste.
Sam adds personality to Animal Hospital while genuinely easing the workload after a brutal event. His design, backstory, and quirks make him one of the more memorable additions in the Hazmat update. If you have not hired him yet, keep an eye out after your next Slime Shift. He is worth every coin.
