For walks, I can take them out for up to an hour. If they need to run, I will have to have my significant other take care of that due to medical conditions on my part. I have several dogs and am used to taking them out until they are tired. For sit-ins at your house, I can bathe/walk them if requested, administer medications if I'm told how (when and how often for pills, and where and how often for shots, etc.), play with them, make sure they go to the bathroom several times a day (or scoop litter boxes if it's a cat), and give them plenty of attention. I can also stay for up to a week if needed. For animals staying at my house, they will mostly stay outside with me or in my room so as to not disturb any of the family pets (or just in my room if they're a cat), I will bathe/walk them if requested (just let me know if there's any special shampoo you'll be giving me), I will make sure they go to the bathroom several times a day and for cats I have my own litter box (but not my own cat), they will get lots of love from me and my family, unless they prefer solitude, and staying time for them would preferably only be a day or two.
