How would you treat dead cats? (TW maybe)

So im watching Flipping Vegas S3 E21 a show where they buy old houses renovate them then sell them at a higher price..... Anyway one of the houses has a pet cemetery at the back.... 4 cat Graves in a line... So the husband offered to dig them up and bury them elsewhere maybe in the woods or even throw them away in the trash if he's too busy for that.... But the wife refused she had professionals dig them up, do a small farewell ceremony and then cremate them all for USD700....so what would u... The husbands method or the wife's method or tell us what u would do? .... Keep in mind these aren't even your cats
