Hopefully the shot will help Claudia. I know that this year has been very bad for allergies as well and it's really affected my Sky. Ziggy may need to be on a different diet. Do you free feed? Many senior cats do better on smaller portions throughout the day. I don't free feed any more. I feed small portions 2 times in the morning and then 2 times in the evening with about a 2-3 hour time period in between feedings. Lots of prayers and positive thoughts are being sent to both Claudia and Ziggy. Please keep us updated about them.
