Rhonda & Percy
With the adoption of Ginny and George this fall, the only remaining Weasley siblings are PERCY and RHONDA, which is purrfect because these two lovebirds absolutely adore each other. When they are not engaged in their favorite activities (loafing for Percy, and gaming for Rhonda), this pair is always together, either snuggling or hurling themselves at their foster humans for attention (Rhonda is particularly adept at becoming one with the floor in front of you, should you deign to walk away before paying your respects). While they are a bit less extroverted than their siblings to start, once you've won them over they are guaranteed to be yours forevermore.
Rhonda and Percy are vaccinated (FVRCP and rabies), microchipped, FIV/FeLV tested, and spayed/neutered. Want to make your life 1000% better? These two will do it.
