omg my cats chased this lizard and i cant belevie my eyes!!!!!!?

well... i came home from a resort vacation. and when i was pulling up i saw my three cats chasing a lizard under the door.. so i locked my cats up, grab the lizard and put him in my old lizards tank ,,i don't have my old lizards anymore and i was planning to get rid of the tank the same day, but i found this lizard.. i researched and it looks like a alligator lizard, so right now it is in a 60 gallon tank with a water dish a big branch that i bought from a store for my last lizards.....and there is sand as bedding and i have two lights for him i am going to buy him crickets tomorrow so is there really anything else i should do?

thank you so much, really appreciated!
