In two words, Mariah was a professional JOY! I have 2 very demanding animals. One is an 85 pound German Shepard who speaks only German. The other is a 9 pound cat, needier than any dog I've ever owned. Not only did Mariah excel at learning the german commands for my energetic pup, Sampson, but she also handled the tense energy flawlessly between him and the cat...who at the time, we had only had for 1 month! My husband and I were in the process of integrating the cat into a dog's world (STRESSFUL TO SAY THE LEAST!). But lucky for us, when we had to jet out of town, Mariah was patient in our chaotic household, never put the two animals in danger, and most importantly, respected their boundaries by following our very detailed demands. We had her coming over 4 times a day for food, play time, walks, and snuggles. Our pets were never lonley thanks to Mariah, and they loved the comfort of staying at home instead of boarding them. Mariah is definitely someone who I now have saved in my phone book. Not only do our pets just adore her, but we do too!
