It is a respiratory infection DO NOT TAKE TO A SHELTER THEY WILL PUT THE POOR LITTLE ANGEL TO SLEEP ASAP WITH OUT CARING FOR IT!!!... the sweet little baby needs 10-14 days of clavamox.... take to the vet and care for the sweet baby your self at home.... the little baby picked your place to come to for a reason.... so doctor it up.... love it and give it a loving home.... I say this as i sit here and look down at one that was in the same shape with the same thing.... cost me $90 to get him the mandatory shots when taking to a vet and the medicine.... those $90 dollars was tough to let go.... but not so tough when i think of those wet little kisses on the cheek every morning when he thinks it is time for mommy to get out of bed and get him some chow... lol @ 4:30 a.m..... the love he gives back is worth more than the $90 .... so please don't give up on the sweet baby.
