Is it wrong of me to “fire” him?

I am going away for a week. I have a lot of animals and needed someone to watch them.

We had a family member that could do it but they can be unpredictable and I was looking for someone to avoid that. My brother recommended his friend that watches houses/pets for a living. Well, I had him come over to meet the animals and he said he thought he could handle it. I requested him to come twice this week (once Monday, once Friday) so that he can get familiar with how to handle them, take care of them, and what to look out for because some of them will fight occasionally and dig which they could hurt themselves doing if the dig out. He cancelled Monday through my brother because he had a chance to see his girlfriend. Then she cancelled on him so he opened his schedule back up to us but never came. He didn’t reach out so I messaged him Tuesday asking why he didn’t make it over. I then asked when he would be available and he never responded. Our last contact was Tuesday when he didn’t respond to my last text. Again, this isn’t just watching animals, this is my family, and if someone getting paid to watch them is so flakey and can’t even come to see how to take care of them how can I trust going away?

I messaged someone else to see if they were still available because to me this is irresponsible and unprofessional. Should I have given it another chance? I can’t stress enough how you cannot just come in here without knowledge of their quirks and how to handle them, which I expressed to him. A lot are rescues and come with problems which can be severe. Was I wrong for asking someone else?
