According to Dr. Barchas from Catster.Com all cats – indoor and outdoor – should have the following vaccines every three to four weeks, beginning at six to eight weeks of age, and ending at 16 weeks: feline viral rhinotracheitis, calci and panleukopenia or FVRCP for short. These should be boostered when the cat is a year old and repeated every three years thereafter.
I hope they are both up on their feet again…I’m missing their usual antics.
